X-Ray fluorescence analysis (XRF) is the best suited analytical technology for grade control of industrial minerals. Simple sample preparation makes it a practical and fast method. Energy dispersive X-ray fluorescence spectrometry (EDXRF) is very common for the control of mining operations and determination of final product grade as modern instruments are easy to use and offer advanced analytical performance.
EDXRF instruments are typically very compact (normally benchtop size) and offer a very low cost of ownership which makes them attractive for dedicated analytical tasks. Sensitivity for light elements such as sodium and magnesium was until recently poor due to the thick detector window which absorbed nearly all radiation from light elements. Modern detector technology combined with high power direct excitation and a thin stabilized entrance window make the EDXRF spectrometer S2 RANGER with the XFlash® LE detector far superior compared to other instruments.
This lab report demonstrates the analytical performance of the S2 RANGER with XFlash® LE detector and Ag target X-ray tube for the analysis of different geological materials with GEO‑QUANT M.
