What is x-ray fluorescence?

X-ray fluorescence is a non-destructive testing method used to determine the chemical composition of different materials. Every element has a distinct number of protons, and its electrons are arranged in shells, with each shell having a different energy level. These energy levels are always the same for atoms of the same type. Electrons always fill lower shells first, and emit energy when they move from one level to another.

XF Analyzer

A portable x-ray fluorescence analyzer will emit x-rays onto the surface of the test material which will eject electrons from the test object. This causes other electrons to move from higher shells to take their place and this transition emits a new x-ray, from the material being tested, with a certain energy that can be measured and linked to a certain element. The quantity of rays that are detected with the same ionization energy is also used to calculate the amounts of each different element in the test material.

X-ray fluorescence is used in mining, soil surveys, in the petroleum industry, cement production, quality control in metallurgy, field analysis in geological studies, and more.

Here at AXIS we do a variety of testing applications with our analyzer.  We are able to test for light materials, including Aluminum and Manganese. Our clients receive a clear Automatically generated report for ease of understanding and clarification.
