7 1 Introducing Chromeleon-PA 1.1 Introducing Chromeleon-PA Dionex Chromeleon-PA is a client/server-based chromatography data system that provides software control of the DX-800 Process Analyzer. Chromeleon-PA is an extended version of the Dionex Chromeleon chromatography data system. Chromeleon-PA adds process monitoring functions to the Chromeleon chromatography functions. These functions include sample stream selection, sample preparation and analysis, configuration of alarms and conditional responses, and component data trending. The following sections provide an overview of Chromeleon-PA's main features. Chromeleon-PA Components These are the Chromeleon-PA main components: Chromeleon Server Configuration program: This program contains configuration information about the chromatography instrument systems that are in the DX-800 Process Analyzer. This program is a standard component of the Chromeleon chromatography data system. Chromeleon instrument server: The server controls the data exchange between the DX-800 Process Analyzer and the Chromeleon-PA computer. Chromeleon Server Monitor program: This program is required for starting and monitoring the chromatography server. This program is a standard component of the Chromeleon chromatography data system. Chromeleon program: This program is the Chromeleon client user interface for accessing chromatography data and for controlling individual chromatography instruments. This program is a standard component of the Chromeleon chromatography data system. Analyzer program: This program is the user interface for accessing process analytical functions. This includes all analyzer-level configuration, control, results display, and results reporting. This program is unique to Chromeleon-PA. Doc /03 1

8 Chromeleon-PA Analyzer Datasource: This is the database in which Chromeleon-PA data is stored. Chromeleon-PA OPC Interface (Optional): The Chromeleon-PA OPC (OLE for Process Control) Server allows access to, and limited control of, one or more DX-800 Process Analyzers by an external OPC-compatible program (the client). The OPC client uses DX-800 data and/or alarm and event information for custom applications. The Chromeleon-PA OPC interface specifications are based on the Axeda FactorySoft OPC Toolkit. Refer to Setting Up Chromeleon-PA (Document No ) for details about the Chromeleon-PA OPC interface. The above programs, as well as the datasource and instrument server can be installed on a single computer or on separate computers, as in the following example: 2 Doc /03

9 Introducing Chromeleon-PA Instrument Configuration Before Chromeleon-PA can operate the DX-800 Process Analyzer, it needs to know what instruments are to be controlled and how they are connected. The Chromeleon Server Configuration program is used to define the instruments in your analyzer systems. A typical system consists of a CC80 Component Controller, an analytical pump, and a detector. After the systems are configured, they are assigned to analyzers. A typical analyzer consists of one or more systems combined to operate in parallel. An analyzer is configured to sequentially monitor from 1 to 21 samples. If more than one sample will be monitored, an optional SS80 Sample Selector is installed on one of the systems. Chromeleon-PA can control a total of four systems configured in up to four analyzers. The example in the figure below shows four systems configured into two analyzers. Doc /03 3

10 Chromeleon-PA Analyzer Instrument Control and Data Acquisition The individual systems handle all low-level instrument control and data acquisition functions. Programs (created in Chromeleon) contain the commands required for controlling instrument functions. Sample analysis sequences (created in the Analyzer program) define the order in which samples are analyzed. Chromeleon-PA coordinates all instrument control, sample selection and preparation, injection, and data acquisition functions, as shown in the figure below: Data Processing and Trending At the end of each analysis, Chromeleon-PA processes the data as specified in the quantification (QNT) method assigned to the system. In addition, Chromeleon-PA allows data trending (monitoring of data over time). Trend data is displayed graphically on the trend plot. Unlike Chromeleon, which can be connected to multiple datasources, Chromeleon-PA can be attached to only one Chromeleon datasource at a time. All data from the configured analyzers is stored and retrieved from this single datasource. The datasource contains all sample data as well as all other information related to the analyzer: the Chromeleon Audit Trail, Analyzer Event Log, report templates, alarm configurations, and so on. Chromeleon-PA 4 Doc /03

11 Introducing Chromeleon-PA determines the folder structure of the datasource where sample data and other types of data is stored. Reporting Chromeleon-PA provides several reporting and printing options. Individual sample reports can be printed after each sample run is completed. Summary reports can also be scheduled to print at specified intervals (for example, daily or weekly). Scheduled summary reports can be created for individual analyzers, streams, and/or systems. Report definition files that define what information to include in the report and how to organize the report are created in Chromeleon. The schedule for when a report should be printed is specified in the Analyzer program. 1.2 About the Chromeleon Datasource Chromeleon-PA can be attached to only one datasource at a time. All data (including sample data, the Audit Trail, the Analyzer program Event Log, report templates, alarm configurations, and so on) is stored and retrieved from this datasource. Chromeleon-PA creates the folder structure of the datasource Datasource Folder Structure When timebases (systems) are created in the Server Configuration program, Chromeleon creates a top-level folder in the datasource for each configured system. All programs (PGM files), methods (QNT files), and report templates (RDF files) for a system must be stored in this top-level folder. These files are used as templates during daily operation, as described below. During daily operation, when the analyzer begins the first sequence of the day, Chromeleon-PA creates a new folder under the system top-level folder and names it with the current year, month, and day. All sequences started on that day are then placed in this subfolder. Each sequence is named with a 6-digit number to ensure uniqueness. Output PGM and QNT files, which are copied from the template versions located in the Doc /03 5

12 Chromeleon-PA Analyzer top-level folder, are also stored in the sequence folder. You can view the datasource structure in the Chromeleon Browser Changing the Current Datasource 1. To change the current datasource, select Datasource from the Administration menu. This opens the Datasource dialog box. 2. In the Available Datasources box, select the desired datasource and click Make Current. The Available Datasource box contains all of the datasources currently connected in Chromeleon. If a particular datasource does not appear in the available list, check to see if it is connected in Chromeleon. 6 Doc /03

13 Introducing Chromeleon-PA 1.3 About the Analyzer Program User Interface The Analyzer program user interface is designed to let you easily access program functions. The following sections describe the main features of the user interface Program Tabs Clicking one of the three tabs on the Analyzer program window (Configuration, Run, or Trending) displays a page with controls for the selected program function. Use the Configuration page to configure analyzers and systems before starting sample processing. Use the Run page to control processing of sample streams on the configured analyzers and systems. Use the Trending page to view a graphical display of selected data over time Window Panes Each program page is divided into left and right panes. On the Configuration and Run pages, use the left pane to configure analyzers. On the Trending page, use the left pane to define trend lines. The settings selected on the left pane determine the information displayed on the right pane. For example, on the left pane of the Configuration page, select an analyzer name to display configuration properties for the analyzer, or select a system name to display configuration properties for the system. The right pane provides access to most Analyzer program functions. Use the right pane of the Configuration page to configure streams, sequences, and result-based events. Use the right pane of the Run page to control analyzer sequence batch and manual sample runs, and to control runs on individual systems. Use the right pane of the Trending page to view plots of the trend lines defined on the left pane. Doc /03 7

14 Chromeleon-PA Analyzer Notes: To hide the left pane, click. To show the left pane when it is hidden, click the vertical bar on the left side of the page. To change the width of the left pane, point to the right edge of the pane. The cursor changes to left and right arrows. Drag the pane to the desired size Alert Bar Whenever an event occurs in the Analyzer program (for example, a sequence is started or an error occurs), the information is displayed across the alert bar above the program tabs. After the event is displayed in the alert bar, it is added to the Event Monitor (see Section 1.4) Status Bar Status information for the analyzers and systems is listed across the bottom of the program window. You can allow the status to scroll through the analyzers and systems, pausing at each one to briefly display status information, or you can lock the display to view only a selected analyzer and/or system. To lock the status bar display, select the analyzer or system that you want to view and then click the unlocked icon. The icon changes to locked. The status bar will now display status for only the selected (locked) analyzer or system. In the example status bar shown below, Analyzer 2 is running Sample 1. The system status is locked on System_A, which is currently running a program named CC84. 8 Doc /03

15 Introducing Chromeleon-PA 1.4 About the Event Monitor Whenever an event occurs in the Analyzer program (for example, a sequence is started or a report is printed), the Analyzer program displays the event in the alert bar at the top of the window. The information is displayed across the alert bar and then added to the list of events in the Event Monitor window. A notice next to the Show Event Monitor button displays the number of new items in the list. Clicking Show Event Monitor opens the Event Monitor window. The Event Monitor lists all Analyzer program events that have occurred in the past 7 days. Notes: If an analyzer or system is removed from the configuration, events generated for the analyzer or system before it was removed will remain on the list for 7 days after they were generated. The items listed in the Event Monitor are separate from and supplemental to the Audit Trail in Chromeleon. Items shown in the Audit Trail do not appear in the Event Monitor and vice versa. For example, when running a sequence, the Event Monitor lists events related to the analyzer (analyzer started, stream in use, analyzer run completed, etc.), while the Audit Trail lists messages related to individual system control (start of sample, inject, autozero, acquisition on, etc.). Doc /03 9

16 Chromeleon-PA Analyzer Filtering the Event Monitor List Each entry in the Event Monitor List indicates the following details: The event type ( error, warning, or information) The event category (hardware, software, report, or component). The analyzer and system that generated the event. You can filter the list using one or more of these conditions. If filter conditions are not currently displayed in the window, click Show Filter Conditions. Then, select or clear the check boxes to view the desired set of events Resizing the Event Monitor Window and Column To resize the Event Monitor window, position the mouse at the lower right corner of the window and drag. To change the width of a column, position the cursor on the right border of the column and drag. 10 Doc /03

17 2 Configuring Analyzers 2.1 About Configuring Analyzers and Systems Use the Configuration page to configure analyzers and systems before starting sample processing. Analyzer configuration consists of the following basic steps: Assigning one or more chromatography instrument systems to the analyzer The systems assigned to an analyzer configuration operate synchronously to analyze a series of process sample streams. Configuring each system Each system in the analyzer configuration is assigned default control programs, a quantification method, a confidence interval, a report format, and alarm parameters. Defining the streams to be analyzed An analyzer can include definitions for up to 100 streams. These include the SS80 valve positions (either 7, 14, or 21) and one or more non-valve streams (these are typically, calibration and check standards). Each stream is assigned a name and a type (calibration, check standard, sample stream, blank, or matrix). Optionally, each stream can be assigned sample preparation parameters (program, injection volume, and internal standard amount), which override the default parameters assigned to each system. Defining sequences The sequences defined for an analyzer can be used for various functions, such as running sample analyses, calibrating the analyzer, or running check standards. The samples in the sequence can also optionally be assigned sample preparation parameters, which will override parameters assigned to the stream and the system. Assigning default sequences to the analyzer There are four analyzer functions to which you can assign default sequences: (1)routine analyzer runs, (2)startup, (3)calibration, and (4)check standards. Doc /03 11

18 Chromeleon-PA Analyzer Defining result-based events After each sample is run, the results can be compared against pre-defined conditions. If the results meet at least one of the conditions, an event is triggered. For example, if the amount of chloride in a sample exceeds a predefined maximum, the check standard sequence is triggered to run. 2.2 About Creating Instrument Control Programs Instrument control programs are created in Chromeleon with the Program Wizard. This section provides an overview of the types of programs needed for an analyzer, guidelines for creating the programs, and example programs. For details about how to create a program with the Program Wizard, refer to the Chromeleon Help. The Analyzer program lets you assign the following four types of programs to a system: Program Type Default Standby Shutdown Overlap Flush Used For Running sample analyses. Placing a system in standby. Shutting down a system. Flushing when a sequence is interrupted (for example, if an alarm occurs). The Chromeleon Program Wizard is designed primarily for creating programs for sample analyses (default). Default programs include commands for injection and data acquisition, which are not used with the Standby, Shutdown, and Overlap Flush programs. When you use the Program Wizard to create a Standby, Shutdown, or Overlap Flush program, delete the following commands from the program after completing the Wizard: Autozero ECD_1.AcqOn ECD_1.AcqOff 12 Doc /03

19 Configuring Analyzers Example Programs Chromeleon-PA provides example program files, which you can refer to when creating programs for your analyzer. Because every program is created for a specific system and application, the examples will not work as is with your analyzer, but the principles behind the types of commands included and the order in which they are listed can be applied to many systems. Refer to Setting Up Chromeleon-PA (Document No ) for printouts and descriptions of the example programs. The example programs are included in the CM-PA Example datasource on the Chromeleon-PA installation CD. To connect to the datasource and view the examples, insert the CD in the drive, go to the Chromeleon Browser, and select File>Mount Datasource>Browse. 2.3 About Creating Method (QNT) Files Quantification method files are created in Chromeleon using the QNT Editor and stored in each system's top-level folder in the Chromeleon datasource. These files are used as templates during daily operation as described below. During daily operation, when the Analyzer program runs a sequence, it copies the template method (QNT) file from the system s top-level program and saves it with the sequence. If a sequence includes calibration standards, both the sequence copy of the method and the template method are updated. This ensures that the updated calibration information is used for all subsequent sequence runs on that system. The steps below provide an overview of how to create a method file for Chromeleon-PA. For detailed instructions, refer to Chromeleon Help. In the Chromeleon Help keyword index, select QNT Editor>Actions. Complete the following steps in the Chromeleon client. 1. Create a new method file (select File>New>Method File) or copy one of the example files included in the Dionex Templates>IC Applications folders and modify it as required for your system. 2. In the QNT Editor, select the General tab page, and select the Fixed Mode under Global calibration settings. Doc /03 13

20 Chromeleon-PA Analyzer 3. Create a sequence that runs the desired number of levels and replicates of the calibration standards. 4. Run the standards. 5. In the QNT editor, select the Calibration tab and add the standards to the table (right-click and select Insert Standard). 6. On the Amount Table tab page, enter the amounts of the components in the standard. 7. On the General tab page, click the Calibrate button to generate the calibration curve and parameters. 8. Save the calibrated method file in the top-level folder for the system. 2.4 Adding Analyzers and Assigning Systems Analyzers are added from the configuration tree (the left pane on the Configuration page). To go to the Configuration page, select the Configuration tab. If the configuration tree is hidden, click the vertical bar on the left side of the page. Note: An analyzer s configuration cannot be changed while it is running About the Configuration Tree The first time the Analyzer program is started, the configuration tree contains a single branch labeled Unassigned Systems. This branch lists systems that were configured in the Chromeleon Server Configuration program and that are not yet assigned to an analyzer. 14 Doc /03

21 Configuring Analyzers If analyzers have already been created, the configuration tree shows the existing analyzers and the systems assigned to them. Unassigned systems (if any) are listed after the analyzers Guidelines for Adding Analyzers An analyzer can include up to four systems. Only one system with an SS80 Sample Selector can be included per analyzer. If your configuration includes more than one SS80, create a separate analyzer for each one. System names cannot be changed from the Analyzer program. These names are assigned in the Chromeleon Server Configuration program How to Add a New Analyzer 1. Click Add Analyzer. A new analyzer is added to the tree. 2. Type a name for the analyzer and press the Enter key. 3. Drag a system from the Unassigned Systems list to the new analyzer. 4. Repeat Step 3 to assign additional systems (if any) to this analyzer. 5. Create additional analyzers, if required for your configuration requirements. Doc /03 15

The Confidence Interval is the range in which the true calibration curve will be found with a given probability. You can select the probability at which the values for a check standard should fall within the confidence interval. The following options are available: 90%, 95%, 98%, 99%, 99.7% 99.8%, 99.9%, and 99.99%. 9. In the Hardware Alarms table, specify the system response to each type of alarm. Alarm Types Alarm Type Fatal HW Non-fatal HW TTL-1 In, TTL-2 In,... TTL-8 In Description An error has occurred that requires the sequence to be aborted. The Analyzer program runs the shutdown program (if possible). If the alarm is caused by a serious system error (for example, the pump pressure exceeds the maximum limit) internal system commands are used to shut down the system. An error has occurred in a CC80 module (for example, a leak is detected or the temperature is not ready), but the sequence is not aborted. An external device connected to a CC80 TTL input has detected a condition or an error and sent a TTL signal (usually an open circuit). 18 Doc /03

27 Configuring Analyzers How to Override the Default Sample Prep Parameters When a system is configured, a default program is assigned to it, and the injection volume and internal standard amount are both set to default values (20 and 1, respectively). These default parameters are used for most samples. However, some samples, especially calibration standards, check standards, and samples that differ significantly from the rest, may require different sample preparation steps. If this is the case, follow the steps below to assign different sample prep parameters and override the sample parameters specified in the system configuration. See Section 3.3 for additional information. 1. One or more vertical bars, labeled Sample Prep. (System Name) are located to the right of the Stream Type column. Click a bar to display the sample preparation parameters for that system. 2. Select the Override check box. 3. Select the desired sample preparation parameters: Program: Select the instrument control program that will be used to run the stream. The drop-down list contains all of the available programs for the system (created in Chromeleon).

Note: If multiple result-based events occur simultaneously, the event with the highest priority takes precedence Configuring Alarms About Alarms The Analyzer program provides several types of alarms. Hardware alarms are triggered when an error occurs in a system module (analytical pump, detector, component controller, etc.). Hardware alarms are classified as either fatal (the sequence is aborted) or non-fatal (the sequence is not aborted). TTL input alarms are triggered by an external device connected to a CC80 TTL input. For example, a liquid sensor on a sample pipe triggers a TTL alarm if the sample pipe is dry. Result-based event alarms are triggered when the results from a run meet a pre-defined condition. For example, if the amount of chloride in a sample exceeds a pre-defined maximum, the check standard sequence is run Alarm Configuration The configuration properties for each system in an analyzer determine how the analyzer responds when a hardware or TTL alarm occurs. The response to each type of alarm can be different. In addition, multiple responses can be assigned to each alarm. For example, a non-fatal hardware alarm can be configured to turn on a CC80 front panel light and to also place the system in standby. The properties of the result-based events defined for each stream in an analyzer determine how the analyzer responds when an event occurs. Multiple result-based events can be defined for each stream. A resultbased event definition consists of a condition (for example, a component amount over a set limit) and a response (action) (for example, running a 30 Doc /03

37 Configuring Analyzers check standard or a calibration sequence). Result-based events can also turn on a CC80 front panel light and/or open a relay output. The following table summarizes the possible responses for each alarm type (fatal hardware, non-fatal hardware, TTL in, and result-based events): Alarm Response *One action per alarm. Fatal HW Non- Fatal HW TTL in Open Relay Out 1 or 2 on the CC80 X X X X Turn on CC80 front panel light 1, 2, 3, or 4 X X X X Trigger an Action:* Shutdown the system X X X X Ignore the alarm X X X X Place the system in standby X X X X Bypass one or more sample streams Additional actions for RBEs only: run sequence, calibrate, standby (analyzer), re-run: alarm on failure, re-run: check standard: calibrate on failure, re-run: check standard: standby on failure, check standard: calibrate on failure, check standard: continue on failure X RBE Note: Multiple alarms (of any type) can be assigned to the same CC80 panel light or relay output. When configuring alarms, it is helpful to assign the same type of alarm to a particular light or relay. For example, you could assign fatal hardware alarms to light 1, non-fatal hardware alarms to light 2, TTL input alarms to light 3, and result-based events to light 4. X Doc /03 31

38 Chromeleon-PA Analyzer Alarm Priorities If multiple alarms occur simultaneously, the Analyzer program responds to them according to the action assigned to each. The priority of actions is as follows: 1. Shutdown action 2. Standby 3. Bypass Streams 4. Ignore If multiple result-based events occur simultaneously, the Analyzer program responds to them in the order in which they are listed on the Result-Based Event tab page in the Analyzer Configuration How Alarm Lights and Relays are Cleared If a hardware alarm occurs that turns on a CC80 front panel light or a relay output, the Analyzer program turns off the light or relay when the cause of the alarm no longer exists. If the alarm caused the system to be shut down or placed in standby, the Analyzer program turns off the light or relay when the system is online again (provided the cause of the alarm no longer exists). If a result-based event occurs that turns on a CC80 front panel light or activates a relay out, the Analyzer program turns off the light or relay only when the same stream is re-run and the result condition does not recur. If a light or relay is cleared for one alarm, but another alarm condition exists for the same light (or relay), the light or relay will immediately turn on again. This will continue happening until all alarm conditions are cleared. See Section 3.11 for additional information. 32 Doc /03

39 Configuring Analyzers Configuring Hardware Alarms The Analyzer program provides several types of alarms, which can be configured for each system in an analyzer. For an overview of the different alarm types, see Section Select the Configuration tab to go to the Configuration page. Display the configuration tree (click the vertical bar on the left side of the page) if it is hidden. 2. In the configuration tree, click the system name. Configuration parameters for the selected system appear on the right side of the window. 3. In the Hardware Alarms table, specify the following for each type of alarm: Response (Action): Shut Down: The system is shutdown. Ignore: The alarm is ignored. Standby: The system is placed in standby. Bypass Streams (available for TTL alarms only): One or more selected streams are bypassed. Panel Light (1-4): Enter 1, 2, 3, or 4 to turn on the corresponding light on the CC80 front panel, or enter None if you do not want a light to turn on. Doc /03 33

40 Chromeleon-PA Analyzer Notes: Relay Out (1-2): Enter a 1 to open Relay Out 1 on the CC80. Enter a 2 to open Relay Out 2, or enter None if you do not want a relay output to open. Multiple alarms (of any type) can be assigned to the same CC80 panel light or relay out. When configuring alarms, it is helpful to assign the same type of alarm to a particular light or relay. For example, you could assign fatal hardware alarms to light 1, non-fatal hardware alarms to light 2, TTL input alarms to light 3, and result-based events to light 4. The alarms are prioritized according to the response they trigger: (1)shutdown, (2)standby, (3)bypass streams, or (4)ignore. If more than one alarm is assigned to a relay output or panel light, the higher priority alarm is given precedence Bypassing Streams You can set up a TTL alarm that will cause injections from one or more streams to be skipped if the alarm occurs. For example, if a liquid sensor on a sample pipe is connected to CC80 TTL-1 and the pipe is dry, the sensor signals the TTL-1 input. Injections from that sample are then bypassed. 1. Select the Configuration tab to go to the Configuration page. 2. If the configuration tree (the left pane on the Configuration page) is hidden, click the vertical bar on the left side of the page. 3. In the configuration tree, click the system name on which the streams to be bypassed are processed. Configuration parameters for the selected system appear on the right side of the window. 4. In the Alarms table, under Response (Action), select Bypass streams for the TTL input that will be used to trigger the alarm. For example, if a liquid sensor is connected to TTL-1 on the CC80, select Bypass in the TTL-1 in Response (Action) cell. The Streams to Bypass cell is enabled. 5. Double-click the icon in the (select Streams) cell to open the Please specify streams to bypass dialog box. 6. Select the stream(s) to bypass and then click OK. 34 Doc /03

41 3 Analyzing (Running) Sample Streams 3.1 About Analyzing (Running) Sample Streams Use the Run page to control the analysis of sample streams on the configured analyzer(s) and system(s). Sample streams are typically analyzed in sequences that are grouped into a batch. A separate sequence batch is used for each configured analyzer. When multiple systems are configured in the analyzer, the Analyzer program synchronizes each sample run in a sequence. In addition, sample preparation can be overlapped; that is, the CC80 can perform sample preparation for the next sample while the current sample is still running. In addition to running sequences, individual sample streams can be manually analyzed. The Analyzer program allows different sample parameters (program, injection volume, and internal standard amount) to be specified for use at different times. This means that sample preparation for a particular stream can be processed differently, depending on the sample parameters currently in effect. The controls on the Run page also let you take individual systems offline to perform maintenance or calibration functions while the rest of the analyzer continues to run. Offline systems can be brought online without stopping the analyzer, by clicking the Resume button. Note: When a system is offline, Chromeleon is used to control functions, such as calibration. When a system with an SS80 goes offline, the analyzer stops after the current sample completes. Doc /03 35

42 Chromeleon-PA Analyzer 3.2 About Sequence Runs The figure below shows the steps the Analyzer program performs when running samples in a sequence. Sample preparation overlap is turned on. See Section 3.4 for details about sample preparation overlap. 36 Doc /03

43 Analyzing (Running) Sample Streams When samples are analyzed in sequences, all systems configured in the analyzer are synchronized to start at the same time. After analyzing a stream, a system does not inject the next sample until the following events occur: All other systems have completed the current stream and sent their results to the Analyzer program The Analyzer program has evaluated the results for result-based events (RBEs) RBEs (if any) are executed The Analyzer program sends the Analyzer Ready command to begin the next sample stream The Injection Cycle Time expires (if one is specified for the sequence) 3.3 About Sample Parameters The Analyzer program allows different sample parameters (program, injection volume, and internal standard amount) to be specified for use at different times. This means that an injection from a particular stream can be processed differently, depending on the sample parameters currently in effect. When each system is configured, a default program is assigned to that system and the injection volume and internal standard amount are both set to default values (20 and 1, respectively). These sample parameters are used for most samples. However, some samples, especially calibration standards, check standards, and samples that differ significantly from the rest, may require different sample preparation steps. If this is the case, you can assign alternate sample parameters. Sample parameters can be specified in the following places within the Analyzer program: Configuration tab (system selected) (default): A default program must be assigned in the system configuration. The remaining two sample parameters are always set to default values (injection volume=20, internal standard=1). Configuration tab (analyzer selected) Streams page: Sample parameters can be assigned to each stream in the analyzer configuration. If there are multiple systems, different parameters can be used for each system. Configuration tab (analyzer selected) Sequence Editor page: Sample parameters can be assigned to each stream in a sequence. If there are multiple systems, different parameters can be used for each system. Doc /03 37

44 Chromeleon-PA Analyzer Run tab (Manual Sample option selected): Sample parameters can be selected at run time (except when the analyzer is running one of the default sequences). When sample parameters are specified in more than one place, the Analyzer program selects parameters in the following order of priority: Run: If sample parameters are specified for a manual sample run on the Run page, they are always used. Sample parameters specified elsewhere are ignored. Sequence: If sample parameters are not specified on the Run page, the sequence sample parameters are used. Streams: If sample parameters are not specified on the Run page or in the sequence, stream sample parameters are used. System: If sample parameters are not specified elsewhere (run, sequence, or stream), system sample parameters are used. 3.4 About Sample Preparation Overlap To reduce the time between injections, the CC80 can perform the sample preparation functions for the next sample in a sequence while the current sample is still running. The overlapped functions are run while data acquisition or other program commands that do not require the CC80 are being executed. When the CC80 finishes the overlapped functions, the program pauses, if necessary, to allow the currently running sample to finish. Then, the remaining commands (inject, data acquisition, etc.) in the overlapped sample s program are executed. If an RBE 38 Doc /03

45 Analyzing (Running) Sample Streams occurs that requires a different sequence to be run (for example, a calibration), the overlapped sample is flushed from the system before the other sequence is started. Notes: Sample preparation overlap occurs only within a sequence (i.e., the first sample in the next sequence is not prepared until the last sample in the current sequence is complete). Sample preparation overlap is enabled or disabled in the Chromeleon Server Configuration program during setup of the analyzer systems. It is enabled by default. 3.5 Creating Sequence Batches Sample streams are typically processed in sequences that are grouped into a batch list. A separate sequence batch is created for each configured analyzer. 1. To view and edit an analyzer's sequence batch list, click the Run tab. 2. In the configuration tree (the left pane on the Analyzer program window), select the analyzer to be run. 3. On the right side of the window, select Sequence Batch. The table below the Sequence Batch button displays any sequences already in the batch. 4. If the batch is empty, the first line of the table has default settings in all cells. To add the first sequence, change the default settings on line 1 as described below. If the batch already contains sequences, add a new sequence by clicking in the blank cell below the last sequence in the table. Default values for the sequence parameters are filled in. 5. Select the desired values for the sequence you are adding: Sequence Type Default: Selecting Default enters the name of the Default sequence (assigned in the analyzer configuration) into the Sequence Name cell. Alt. (Alternate) Start: Selecting Alt. Start enters the name of the default alternate start sequence (assigned in the analyzer configuration) into the Sequence Name cell. Doc /03 39

46 Chromeleon-PA Analyzer Calibration: Selecting Calibration enters the name of the default calibration sequence (assigned in the analyzer configuration) into the Sequence Name cell. Check Std. (Standard): Selecting Check Std. enters the name of the default check standard sequence (assigned in the analyzer configuration) into the Sequence Name cell. Specify>>: Selecting Specify>> lets you choose to run any sequence available to the analyzer. Choose the sequence to run from the Sequence Name list. Sequence Name: If you selected Specify>> for the sequence type, select the sequence to run from the list. If you selected one of the default sequence types, the name of the default sequence for that type is automatically filled in and cannot be edited. Start Line #: If you selected Specify>> for the sequence type, enter the line number at which the analyzer should begin running the sequence. If you selected one of the default sequences, the line number specified in the analyzer configuration is automatically filled in and cannot be edited. Date/Time Start: Indicates when the sequence will start. Repeat: If you selected Specify>> for the sequence type, select the number of times to repeat the sequence. enter the number of times to repeat the sequence (0 to 99, or continuous). Note: To enter continuous, type a c (or any portion of the word) or type -1 and then press the Enter key. If you selected one of the default sequences, the repeat number specified on the Sequences tab page in the analyzer configuration is automatically filled in and cannot be edited. Suspend Printing: Select whether to suspend printing of end-of-run reports. The default setting is no (do not suspend printing). To suspend printouts, type yes and press Enter. Note: In order to have printouts after each run, the Print End-of-Run option must be enabled in each system's configuration (see Enabling and Disabling End-of-Run Reports) and the Suspend Printing option in the sequence batch must be set to no. 6. To start the sequence batch, click the Start button. The Analyzer program runs the sequences in the order in which they are listed in the batch. 40 Doc /03

53 Analyzing (Running) Sample Streams 3.10 Running a System Offline 1. Take the system offline. See Section 3.9 for instructions. 2. In the analyzer configuration tree (the left pane on the Run page) on the Run page, select the analyzer in which the system is configured and select the system name under the analyzer. 3. Go to Chromeleon by clicking the Direct Control button on the upper-right side of the page. 4. In Chromeleon, create and run any required sequences or perform any required operations under direct control from a panel. 5. To resume operation with the analyzer, first end any runs being controlled by Chromeleon and disable direct control by selecting Monitor from the Control menu. Then, return to the Analyzer program and click Resume to bring the system back online with the analyzer About Processing Result-Based Events The Analyzer program performs the following basic steps when a result-based event occurs after running a sample stream: 1. After the systems run a stream in a sequence, they report the results to the Analyzer program. 2. The Analyzer program checks the results against any conditions defined in result-based events. 3. If a sample result meets one of the conditions, the Analyzer program performs the action specified in the result-based event and (if specified) also turns on a CC80 front panel light and/or a CC80 relay output. See the flow diagrams below for details about how the Analyzer program handles each type of result-based event action. 4. After completing the result-based event action (or if no result-based event occurred) the Analyzer program signals the systems to go to the next stream in the sequence. Doc /03 47

54 Chromeleon-PA Analyzer Result-Based Event Flow Diagrams RBE Action=Continue Summary: Continue If a result-based event (RBE) occurs when the selected action is Continue, the Analyzer program turns on a panel light and/or a relay output if specified in the RBE definition, and then continues to the next line in the sequence. 48 Doc /03

55 Analyzing (Running) Sample Streams RBE Action=Run Sequence Summary: Run Sequence If a result-based event (RBE) occurs and the selected action is Run Sequence, the Analyzer program turns on a panel light and/or a relay output if specified in the RBE definition. The overlap flush program is then run, followed by the specified sequence. When the sequence is complete, the systems continue to the next line in the original sequence. Note: This action is similar to the Rerun: Alarm on Failure action in that a sequence is run if the RBE occurs. However, with this action, the sequence is always run until completion and it cannot be repeated. Doc /03 49

56 Chromeleon-PA Analyzer RBE Action=Calibrate Summary: Calibrate If a result-based event (RBE) occurs when the selected action is Calibrate, the Analyzer program turns on a panel light and/or a relay out if specified in the RBE definition. The overlap flush program is then run on all systems, followed by the calibration sequence. After calibration, the QNT files for each system are updated and then each system continues to the next line in the original sequence. 50 Doc /03

57 Analyzing (Running) Sample Streams RBE Action=Standby (Analyzer) Summary: Standby (Analyzer) If a result-based event (RBE) occurs when the selected action is Standby (Analyzer), the Analyzer program turns on a panel light and/or a relay out if specified in the RBE definition. The overlap flush program is run on all systems, followed by the standby program. The analyzer remains in standby until you click Resume on the Analyzer program Run page. Then, each system continues to the next line in the sequence. Doc /03 51

58 Chromeleon-PA Analyzer RBE Action=Re-Run: Alarm on Failure Summary:Rerun: Alarm on Failure If a result-based event (RBE) occurs (1), the Analyzer program turns on a panel light and/or a relay output (2) if specified in the RBE definition. The overlap flush program is run and then the sample is rerun (3). If the same RBE does not re-occur when the sample is rerun, the analyzer continues to the next line in the sequence (4). If the same RBE re-occurs, the Analyzer program starts running the alarm sequence (5). After each line in the alarm sequence is completed, the Analyzer program checks for RBEs. If no RBEs occurred, the alarm sequence 52 Doc /03

59 Analyzing (Running) Sample Streams is ended, and the analyzer then continues to the next line in the original sequence (6). If an RBE occurs and the alarm sequence has not been completed, the next line in the sequence is run (7). When all of the lines in the alarm sequence have been run, the Analyzer program checks whether a repeat is requested. If so, the alarm sequence is restarted (8). When there are no more repeats, the analyzer continues to the next line in the original sequence (even if RBEs are still occurring) (9). Note: This action is different from the Run Sequence action in that the sequence does not continue running if no RBE occurs. Also, if the alarm sequence runs to completion, it can be repeated.

61 Analyzing (Running) Sample Streams Summary:Rerun: Check Standard: Calibrate on Failure If a result-based event (RBE) occurs (1), the Analyzer program turns on a panel light and/or a relay output (2) if specified in the RBE definition. The overlap flush program is run and then the sample is rerun (3). If the same RBE does not recur when the sample is rerun, the analyzer continues to the next line in the sequence (4). If the same RBE recurs, the analyzer runs the check standard sequence (5). If the check standard sequence fails (as determined by the QNT file and the confidence interval specified for each system), the calibration sequence is run (6). After calibration, the QNT file for each system is updated and then the analyzer continues to the next line in the sequence (7). If the check standard sequence passes, the Analyzer program starts running the alarm sequence (8) (if one exists). After each line in the alarm sequence is completed, the Analyzer program checks for RBEs. If no RBEs occurred, the alarm sequence is ended, and the analyzer then continues to the next line in the original sequence (9). If an RBE occurs and the alarm sequence has not been completed, the next line in the sequence is run (10). When all of the lines in the alarm sequence have been run, the Analyzer program checks whether a repeat is requested. If so, the alarm sequence is restarted (11).

63 Analyzing (Running) Sample Streams Summary:Rerun: Check Standard: Standby on Failure If a result-based event (RBE) occurs (1), the Analyzer program turns on a panel light and/or a relay out (2) if specified in the RBE definition. The overlap flush program is run and then the sample is rerun (3). If the same RBE does not re-occur when the sample is rerun, the analyzer continues to the next line in the sequence (4). If the same RBE re-occurs, the analyzer runs the check standard sequence (5). If the check standard sequence fails (as determined by the QNT file and the confidence interval selected for each system), the Standby program for all systems in the analyzer is run (6). The analyzer then idles (runs existing conditions) until you click Resume on the Analyzer program Run page. When Resume is selected, the analyzer continues to the next line in the sequence (7). If the check standard sequence passes, the Analyzer program starts running the alarm sequence (8) (if one exists). After each line in the alarm sequence is completed, the Analyzer program checks for RBEs. If no RBEs occurred, the alarm sequence is ended, and the analyzer then continues to the next line in the original sequence (9). If an RBE occurs and the alarm sequence has not been completed, the next line in the sequence is run (10). When all of the lines in the alarm sequence have been run, the Analyzer program checks whether a repeat is requested. If so, the alarm sequence is restarted (11).

75 4 Reporting 4.1 About Reporting The Analyzer program provides several reporting and printing options. Individual sample reports can be printed after each sample run is completed. Summary reports can also be scheduled to print at specified intervals, for example, daily or weekly. A scheduled summary report can include information for all analyzers, streams, and systems; or just the analyzer, stream, and/or system of interest. Report templates define the information to be included in the report and how it is organized. Templates are created in Chromeleon. See Section 4.2 for details. The schedules for when to reports should be printed are created in the Analyzer program. 4.2 About Report Templates Note: This topic provides a brief description of report templates and how they are created. For detailed information, refer to the Chromeleon Help. In the Help keyword index, select Printer Layout>Actions. Report templates determine the contents and organization of reports printed from the Analyzer program. The Analyzer program uses two basic types of report templates: End-of-run templates: These templates determine the contents of reports printed at the end of each sample run. An end-of-run report template is assigned to each system when it is configured on the Analyzer program Configuration page. An end-of-run report typically includes a chromatogram, a table containing information (height, area, amount, etc.) about each peak in the chromatogram, calibration curves and tables, and peak analysis information (height, width, type, resolution, etc.). Scheduled summary report templates: These templates determine the contents of reports printed at scheduled intervals. A report template is assigned to each Doc /03 69

76 Chromeleon-PA Analyzer scheduled report when it is created in the Analyzer program Manage Reports dialog box. A scheduled summary report typically includes summary information and trend data plots. Report templates are part of the report definition files created in Chromeleon. A report definition file has two purposes: it determines the sample information shown on the screen in Chromeleon (the screen report) and it determines the contents and organization of printed reports (the printer layout). For the end-ofrun and schedule report templates used in the Analyzer program, the printer layout portion of the report definition file is most relevant. Chromeleon provides example report definition files, which can be used either without modification or customized for your needs. The examples are available in the Chromeleon Browser in the Dionex Templates>Reports folder. When Chromeleon-PA is set up, report definition files (templates) are created for each system. Refer to Setting Up Chromeleon-PA (Document No ) for details. Note: Because you typically do not want a printout of every sample in a scheduled report, the example scheduled report template prints the last sample in the sequence only. 4.3 Enabling and Disabling End-of-Run Reports 1. Click the Configuration tab. 2. In the configuration tree (the left pane on the Analyzer program window), select the analyzer and then select the system. To display the configuration tree if it is hidden, click the vertical bar on the left side of the page. 3. On the right side of the window, select or clear the Print End-of-Run Report check box. If you select the check box, select the report template from the drop-down list. See Section 4.2 for more information. Note: You can temporarily disable (suspend) end-of-run reports on the Run page. See Section 3.5 for more information. 70 Doc /03

77 Reporting 4.4 Scheduling Reports You can schedule printing of reports at specified intervals. A scheduled report can include information for all analyzers, streams, and systems; or just the analyzer, stream and/or system of interest. 1. Click the Reporting button at the top of the Analyzer program window to open the Manage Reports dialog box. 2. Click the Add button. 3. Under Report # Properties, select how often to print the report, what information to include, and the report format. Under Interval, select how often to generate the report (the time between each report). For example, to print a report every 12 hours, select 12 and Hour(s). In the Beginning field, enter the starting date and time at which to begin counting the interval. For example, if the interval is 12 hours and you select today's date and the current time, the first report will print 12 hours from now. The Beginning date/time can be either in the future or in the past. In the Span field, select the range of data (the number of seconds, hours, days, weeks, or months) to be included in the report. The span begins at the specified number of seconds, minutes, hours, etc., before the first report is scheduled to print. For example, if the first report is scheduled to Doc /03 71

78 Chromeleon-PA Analyzer print at 6:00 and the Span is 1 hour, the report will contain data from samples with an injection time between 5:00 and 6:00. This example schedules a report to print once a week (Interval=1 week). The first report will print on Thursday Jan 08 at 9:00 (1 week from the Beginning date/time). It will contain data from all samples that have an injection time between Thursday Jan 01 and Friday Jan 02 (Span=1 day). The contents and format of the report is determined by the Format named Summary (System_A). Subsequent reports continue the schedule, printing once a week with data collected the previous day. Analyzer, Stream, System: Select the analyzers, streams, and systems to be included in the report. Format: Select the report template from the drop-down list. Description: Enter a description for the report that will appear in the list of reports at the top of the dialog box, or accept the default description. 4. Click Apply. 72 Doc /03

79 Reporting Note: When you start the Analyzer program after a shutdown, the Analyzer prints the first report that would have printed had the program continued running, and then skips the remaining reports. The schedule then continues at the current date/time. This prevents a large backlog of reports from being sent to the printer. For example, a report is scheduled to print daily and the Analyzer program is shut down for a week. When the Analyzer program is restarted, the first of the seven queued daily reports is printed and the remaining six are skipped. If you specify a Beginning date/time that is in the past, the Analyzer program generates each separate report as required, and then queues them for printing. For example, to schedule a daily report that includes reports from the previous week, set the Beginning date/time to a week in the past and set the Interval to 1 day. The Analyzer immediately generates seven reports and sends them to the printer. Thereafter, a report will be generated once a day. 4.5 Suspending a Scheduled Report 1. Click the Reporting button at the top of the Analyzer program window to open the Manage Reports dialog box. 2. In the list of reports, clear the check box for the report that you want to temporarily disable. Note: To permanently remove a report, select it in the list and click Delete. 4.6 Modifying a Scheduled Report 1. Click the Reporting button at the top of the Analyzer program window to open the Manage Reports dialog box. 2. In the list at the top of the dialog box, select the description of the report to be modified. 3. Click Properties. Doc /03 73

81 5 Trending 5.1 About Trending Trending provides a graphical display of selected data over time (for example, a plot of the peak height obtained for a particular component over the last 24 hours). A particular trend line can show data from all of the configured analyzers, streams, and systems, or can be limited to a single analyzer, stream, or system. In addition to plotting component variables (amount, area, height, retention time, etc.), you can plot instrument-specific variables (the detector's background signal, the pump pressure, etc.) and calculations (for example, the sum of multiple amounts). Multiple trend lines can be defined. They will be displayed simultaneously on the trend chart. Various time range options are available for displaying data. For example, you can display data starting from a specified date/time in the past until the present and have the chart continuously updated, or you can display data between two fixed dates/times. Another option is to display all the data for a window of time (for example, the previous two days). The combination of the defined trend lines, selected time range, and other viewing options determine the contents of the trend chart, or the trend view. Trend views can be saved and then reopened later. They can also be deleted. Doc /03 75
