X-RAY FLUORESCENCE (XRF) :

The most common chemical analytical technique used is X-ray fluorescence spectrometry (XRF), which can determine the proportions and identity of the major oxides of materials of widely differing composition such as silicates, carbonates, sulphates and phosphates from below 0.01% to 100%. The analysis is rapid and non- destructive, but is generally impractical for determining elements lighter than fluorine. X-ray Fluorescence (XRF) analysis provides both qualitative and quantitative compositional information.

X-ray fluorescence is the emission of fluorescent X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays.

X-ray Fluorescence analysis is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science and archaeology.
