AN /2010 The Niton XL2 GOLDD Series x-ray fluorescence (XRF) analyzer is the performance choice for your toughest testing applications. Where low detection limits and high sample throughput are critical, our combination of hardware, software, and direct industry experience are combined to provide you with a solution to your most difficult analytical requirements. The chart below details the sensitivity, or limits of detection (LODs) 1, of the Niton XL2 GOLDD using Soil Analysis Mode for an SiO 2 matrix, a typical soil matrix (SiO 2 with Ca/Fe), and SRM matrix. Soil Analysis Mode offers optimum performance for low levels of RCRA metals and other contaminants/constituents found in soil/sediment type samples. LODs are calculated as three standard deviations (99.7% confidence interval) for each element for a 120-second total analysis time.

For limits of detection for elements not shown, please contact a Thermo Fisher Scientific office or your local representative. Limits of detection (LODs) are dependent on the following factors: Testing time Interferences/matrix Level of statistical confidence Please Note: Ongoing research and advancements in our Niton XL2 Series analyzers with geometrically optimized large area drift detector (GOLDD) technology will lead to continual improvement in many of the values detailed in this chart. Contact a Thermo Fisher Scientific office or your local representative for the latest performance specifications. Actual analysis time is based on your requirements, and, in most cases, shorter times will give you the detection limits you require. For example, if analysis time was reduced from 60 seconds/filter to 15 seconds/filter, then the detection limits obtained would be twice the values shown in the chart. Similarly, increasing the analysis time will reduce the detection limits by the square root of the increased time. A/S = Application-specific N/A = Not applicable 1.

With our groundbreaking GOLDD technology, your analytical capabilities are taken to a whole new level. The direct benefits to you include: real-time results, light element analysis, and advanced performance in our value package. The Niton XL2 GOLDD analyzer also includes a standard integrated camera to ensure accurate positioning on the area of interest to capture and store an image for review or inclusion in reports. Ergonomically designed and featuring daylight-readable icons, the Niton XL2 GOLDD incorporates customizable menus, multiple language options, and a standard analytical range of up to 30 elements from magnesium to uranium. Sealed against moisture and dust with 100% embedded software tools, these analyzers are lightweight yet ruggedly built to withstand the harshest environments in the field or on the shop floor. The GOLDD Advantage GOLDD technology delivers vast improvements in sensitivity or measurement times as much as 10-times faster than conventional Si-PIN detectors and up to 3-times more precise than conventional silicon drift detectors (SDD). We achieved this improvement by combining the Niton XL2 GOLDD 45kV, 100 μa x-ray tube, closely optimized geometry, and patented signal processing hardware and software. These advantages are coupled with our drift detector, one of the largest area drift detectors that is commercially available in a handheld XRF analyzer, providing you with superior performance in the form of faster analysis and lower detection limits. The final product is the Niton XL2 GOLDD a more versatile and technologically advanced handheld XRF analyzer, designed without compromise to make you more successful.

3 Niton XL2 GOLDD: Large area drift detector and optimized geometry for more x-ray counts gives you faster and more precise readings. With its unparalleled accuracy, you can be confident that the Niton XL2 GOLDD won t misidentify value, grade, or residuals. The Niton XL2 GOLDD stands alone with its many standard features and available options. By utilizing the standard Thermo Scientific Niton Data Transfer (NDT ) PC software suite to customize the instrument, you can set operator permissions, generate custom reports, print certificates of analysis personalized with your own company logo, or remotely monitor and operate the instrument hands-free from your PC. Integrated USB and Bluetooth communications provide direct data transfer to your PC or networked storage device, eliminating the cumbersome data synchronization procedures required by Windows Mobile -based XRF analyzers.
