What is X-ray Fluorescence (XRF)

X-ray Fluorescence (XRF) is an analytical technique that uses the interaction of X-rays with a material to determine its elemental composition. XRF is suitable for solids, liquids and powders, and in most circumstances is non-destructive. XRF spectroscopy is an effective method for qualitative and quantitative analysis of material composition.
