What is X-ray Fluorescence?

X-ray fluorescence 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. XRF is also used to determine the thickness and composition of layers and coatings. It can analyze elements from beryllium (Be) to uranium (U) in concentration ranges from 100 wt% to sub-ppm levels.

Principles of X-Ray Fluorescence

XRF is an atomic emission method, similar in this respect to optical emission spectroscopy (OES), ICP and neutron activation analysis (gamma spectroscopy). Such methods measure the wavelength and intensity of ‘light’ (X-rays in this case) emitted by energized atoms in the sample. In XRF, irradiation by a primary X-ray beam from an X-ray tube causes emission of fluorescent X-rays with discrete energies characteristic of the elements present in t...
