Elemental Analysis, Process and Quality Control X-ray fluorescence analysis (XRF) one of the best analytical techniques to perform elemental analysis in all kinds of samples, no matter if liquids, solids or loose powders must be analyzed. XRF combines highest accuracy and precision with simple and fast sample preparation for the analysis of elements from Beryllium (Be) to Uranium (U) in the concentration range from 100 % down to the sub-ppm-level. Energy dispersive X-ray fluorescence (EDXRF) is the best choice for dedicated applications in quality and process control with demands for ease of use and compact size. It delivers analytical flexibility for research and monitoring tasks. Wavelength dispersive X-ray fluorescence spectrometry (WDXRF) is known for its unrivalled accuracy, precision and reliability. This robust analytical technology has made its way into all kinds of industrial applications, such as cement, polymers, refineries, mining, and industrial minerals.
