This is the first of three masterclass web seminars covering X-ray Fluorescence, the theory and basics of X-ray fluorescence spectroscopy was presented. Join us for one or all three.

X-ray fluorescence (XRF) is an analytical technique that can be used to determine the chemical composition of 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 100% down to sub-ppm levels. This masterclass explained the theory of XRF, its principles, the different types of XRF spectrometers: wavelength dispersive (WDXRF) and energy dispersive (EDXRF), and its benefits in comparison with other elemental techniques like ICP and AAS.
