What Is XRF ?
XRF or X-ray Fluorescence spectrometry, is a chemical analysis technique used to determine the chemical composition of a wide range of bulk solids, liquids and slurries. The technique is most commonly used for the quality control of materials in industrial applications in the cement, steel and mining and similar industries. It is also often used in the petrochemical industry to monitor the sulfur content of fuels and the quality control of plastics. XRF is a versatile tool and is also found in many university geology departments where its ability to measure a wide range of elements and simple operation make it an extremely useful tool.
