XRF (X-ray Fluorescence)

X-ray Fluorescence (XRF) is an analytical technique used to determine the elemental composition of a material. When a sample is exposed to high-energy X-rays, its atoms absorb this energy and emit secondary X-rays, called fluorescence. Each element emits X-rays at characteristic energies, allowing identification and quantification of the elements present. XRF is non-destructive, rapid, and versatile, making it useful in fields like geology, environmental testing, and materials analysis. It provides accurate, detailed elemental data without extensive sample preparation.
