  • What is XRF? | Spectroscopy Guides

    X-ray Fluorescence (XRF) is a technique widely used in elemental analysis. It is based on the principle that an atom's inner electrons, when bombarded with high energy radiation such as X-rays, are ejected. The atom relaxes by emitting photons of characteristic wavelengths, which are used to identify the element.  If diagrams do not animate, try ...
