The following measured values are determined in a very short time: temperature, conductivity, ph, acid capacity, calcium, magnesium, total hardness and, in parallel, the concentrations of the individual anions. Further Metrohm instruments can be incorporated in the existing system at any time and used to measure additional parameters. Analytical sequence 1. Conductivity is measured in the sample vessel on the sample changer. 2. First sample transfer to the 861 Advanced Compact IC. 3. The IC measurement is started automatically. 4. Second sample transfer to the external cell of the 815 Robotic Sample Processor. 5. Temperature, ph and acid capacity (p and m values) calcium, magnesium and total hardness are determined. The whole procedure is controlled by the TitrIC software: The user enters the sample position and sample identification, IC system and tiamo method, after which TitrIC transfers all the relevant information to tiamo and IC Net. When the measurement has been concluded, TitrIC automatically generates a joint report containing all results. This report can be printed out or produced as an Excel table.

Robotic Sample Processor The sample processor is placed at the side at which it is most easily accessible. Please note that the following procedure refers exclusively to the version in which the 815 Robotic Sample Processor is located at the left-hand side of the system. On the right-hand side of the 815 Robotic Sample Processor, attach the stand support ( ) without the horizontal brace to the tower of the 815 (hexagon screw beneath membrane pump 1). The brace will be installed later. Do not screw the titration head ( ) onto the Swing Head! The Sample Rack supplied is screwed onto the 815. In the vicinity of the 815 the two canisters (standard equipment of 815) are placed on the floor: One 10 L canister is used as a waste container, the second as a reservoir for deionized (DI) water used for rinsing the external cell. From the smaller opening of the canisters containing DI water, an M8 PTFE tubing connection of suitable length is led to the connection box made of white plastic of membrane pump 1 and connected. From the front opening of the waste canister an M8 PTFE tubing connection of suitable length is led directly to membrane pump 2 (black plastic) and connected. A more detailed description is given in the Instructions for Use of the 815 Robotic Sample Processor Conductometer ( ) The 712 Conductometer is placed directly to the right of the 815 Robotic Sample Processor. For detailed information about the usage check the Instructions of Use of the 712. It is recommended to carry out the calibration of the cell constant manually and before tiamo is started up. Consult thereto the Installation Instructions of the 712 Conductometer, chapter But firstly the 712 has to be registered in the configuration of tiamo so that the calibration can be stored. Thereto the calibration should be made later when the 712 is registered and tiamo shut down. 2.3 Titrando ( ) Directly to the right of the 712 Conductometer, place the Titrando with the titration solution (0.05 M EDTA, at the front, with 10 ml Dosing Unit and 800 Dosino) and the auxiliary complexing solution (0.2 M TRIS / 0.1 M Acetylacetone, at the rear, with 20 ml Dosing Unit and 800 Dosino). 2.4 Dosino holder ( ) The Dosino holder ( ) is placed at the back of the Titrando and the 712 Conductometer; the 50 ml ( ) Dosing Unit is screwed and the 20 ml ( ) Dosing Unit is placed with its 0.1 M HCl titration solution onto this holder at a later stage Advanced Compact IC ( ) Place the 861 Advanced Compact IC for anions ( ) to the right of the bottle holder.

Conductivity sensor: Under Configuration / Sensors click on Edit / New / other sensor and enter under Sensor name Conductivity sensor type in the desired sensor information and click on <Ok> Methods The following seven methods are provided: TitrIC 1 - complete run: With this method all the parameters possible with the standard instruments are measured and the IC measurement is initiated. TitrIC 1 - titration and measurement: Only titrations and direct measurements are carried out; the IC measurement is not initiated. In TitrIC under Settings / IC Net settings the IC Anions and IC Cations have to be deactivated, or the method is started up only from tiamo. TitrIC 1 - preparation of titration equipment: This method is used for preparing all titration instruments, i.e., rinsing the tubing connections of the Dosing Units with reagents or deionized water and rinsing the external cell. Start this method only from tiamo not from TitrIC! TitrIC 1 - IC calibration: This method is used for calibrating the IC measurement with standard solutions without having to carry out the titration part of a typical TitrIC measurement; this means that a lot of solution can be saved. TitrIC 1 semi automated ph calibration: With this method the ph electrode is calibrated automated; the buffer solutions are poored into the titration vessel. Start this method only from tiamo not from TitrIC! TitrIC 1 - ph calibration: Here the Aquatrode is taken out of the titration vessel and placed into the buffer solutions. Start this method only from tiamo! TitrIC 1 - titer determination of EDTA: This method is used for the titer determination. Start this method only from tiamo! TitrIC 1 - titer determination of HCl: This method is used for the titer determination. Start this method only from tiamo! An automated conductivity cell calibration method for tiamo can be delivered if desired (titric@metrohm.com); it is recommend to do it manually. Import: Click on Method at the left, then select under File / Method manager / Edit / Import in the directory C:\Program Files\Metrohm\tiamo\methods_titric all methods and click on <Open>. Note! Alterations of these methods should only be carried out by a person at the Administrator level and who is thoroughly familiar with tiamo. Never forget that in TitrIC this new method must be selected in the sample table under Methods tiamo.

15 Page 15/ Configuration of the export template Export template: tiamo must transfer its results to TitrIC in a particular way, which means that the export template must be generated exactly in the following form: Under Database / Tools/ Templates / Export templates / New enter the following: then click on Select fields and enter the following: Configuration of the export template in TitrIC 1 Input window for the export template The entry Start counter is obtained at the left by clicking on Determination / Identification, ID1.Name and ID1.value are obtained at the left by clicking on Sample / Identifications, RS0x by clicking on Results / RS0xxx. By clicking on the upper double arrow in the center the entries can be moved to the right. Of course another number of results than five is possible. Shut down tiamo 1.1!

16 Page 16/ Configuration of IC Net Start IC Net 2.3 Under Options / Global Preferences the following must be marked: under If method changed - Don t ask to save and System file overwrite - Always. With the TitrIC software a predefined IC system is also installed. It s found under C:\Program Files\Metrohm\IC Net 2.3\IC Net\Systems\Anion\anion.smt and C:\Program Files\Metrohm\IC Net 2.3\IC Net\Systems\Cation\cation.smt. Open the two systems, click on Control / Connect to workplace and choose the right COM-Port. If you don t know to which COM-Ports the systems are connected to you have to try out until you have communication between PC and the 861. Work should always be carried out with these systems, as otherwise the result transfer to TitrIC will be disturbed. This is why, if the systems have to be altered, the existing system is always altered and saved under the same name. The suppressor step is not made at the start of the measurement in the usual way, but with Fill directly after the end of the chromatogram. These means that after long pauses between measurements the suppression may no longer function. This is why after longer pauses you should carry out a suppressor step manually and ensure that the injection valve is in the Fill position. Depending on the application and column it may be necessary to adapt the time program in the IC system: Inject should always be carried out right at the start (0.10 min) of the time program, Fill right at the end. In this way you can start to measure with a stable baseline immediately after the sample loop has been filled by the Dosino. If a calibration is carried out later and the new calibration data are to be applied to a sample that has already been measured then this is possible by using TitrIC see the online help of the TitrIC software under Database / Recalculate / Recalculate for the results of several samples. Shut down IC Net Configuration of TitrIC TitrIC is started (tiamo and IC Net are started automatically at the same time) All paths have already been entered as defaults and the system is ready for work. If other paths have been used instead of the default paths then this must be altered in the corresponding dialog under Workplace / Settings /. TitrIC starts tiamo and IC Net at the same time. However, the tiamo window is not visible, but can be brought to the foreground in TitrIC via View / Show tiamo. If TitrIC is shut down then tiamo will also be shut down automatically but IC Net must always be shut down individually. Always shut down TitrIC as the first program! If tiamo is accidentally shut down first then TitrIC is also no longer visible; the program will continue to run in the background. It can then be shut down with a right-hand click on an empty position in the Taskbar and a left-hand click on Task manager / Processes / TitrIC.exe / End process. For further information please consult the TitrIC online help (? / Show Help) or contact the responsible person at your local Metrohm agency. You can also report your problems to the following support titric@metrohm.com. Always start and shut down TitrIC first!
