UniQuant advanced X-ray fluorescence spectrometry solution

Thermo Fisher Scientific, Inc. the world leader in serving science, announced the introduction of the Thermo Scientific UniQuant X-ray fluorescence analysis package now available on the high-performance energy dispersive X-ray fluorescence (EDXRF) system – Thermo Scientific ARL QUANT’X. Featuring the spectrometer, standard-less software and accessories, the complete benchtop EDXRF system meets the elemental analysis needs of central and contract laboratories, as well as environmental monitoring, chemicals, mining, forensics, food, electronics, cement and metals industries. In addition, a camera is integrated with the instrument for sample imaging.

This integrated solution is designed to facilitate rapid qualitative and quantitative non-destructive elemental analysis of samples of any size, shape and state. It is capable of achieving fast and accurate analysis of major, minor and trace elements in a variety of materials including solids, powders, liquids and layered structures.

The Thermo Scientific UniQuant software package achieves superior accuracy based on theoretical models that have been refined specifically to work with the ARL QUANT’X. UniQuant uses eight filters to collect emission lines and excite every sample for truly unambiguous results for all elements from Fluorine (Na) to Uranium (U). Capable of acquiring complete spectral profiles, the software can correct all possible overlaps and background effects, previously too complex to perform due to the nature of multi-condition X-ray excitation and detector resolution.

The software also enables analysts to specify the sample’s properties, such as area, height or mass. These characteristics often have a dramatic effect on the results, especially when the material contains a large fraction of light atoms invisible to EDXRF, such as hydrogen, carbon, nitrogen and oxygen. A variety of selectable reporting levels and formats present the results clearly for any type of user. ARL QUANT’X with UniQuant can be pre-calibrated and ready to operate out-of-the-box with minimal operator training, requiring no expensive calibration packages.

ARL QUANT’X also features an integrated, live sample-imaging camera, which visualizes the samples before or during analysis in order to identify, isolate and align very small features and areas, thus improving the accuracy of standard-less analysis. Additionally, the vacuum, helium and inert gas flush options inherent to the spectrometer considerably improve sensitivity for light-element analysis in solid, powder and liquid samples.

With a cast zinc metal, full-vacuum chamber on a welded anodized steel frame, the design ensures mechanical durability for a lifetime of service, while the small instrument footprint enables easy transportation. This complete turnkey system is exceptionally easy to install and is ready to use within only 30 min. It achieves rapid measurement times of 10-20 s per element for maximum time savings while being fully customizable and upgradeable on site.
