The Basics of Elemental Analysis with XRF – Q&A | …

X-ray fluorescence spectroscopy ( XRF) is a powerful analytical technique that provides both qualitative and quantitative information on a wide variety of sample types including solids, liquids, slurries, and loose powders. It can quantify elements from beryllium (Be) up to americium (Am) in concentrations from down to sub-ppm levels.
