XRF

XRF, or X-ray fluorescence, is a scientific technique used to identify the elements in a material. When a sample is exposed to X-rays, the atoms inside it absorb energy and then emit secondary, or fluorescent, X-rays at characteristic wavelengths. By analyzing these emitted X-rays, researchers can determine which elements are present and in what amounts. XRF is widely used in fields like geology, environmental testing, and quality control because it’s fast, non-destructive, and capable of analyzing a wide range of materials.
