X-ray fluorescence (XRF) 

X-ray fluorescence (XRF) analysis is a non-destructive analytical technique used to determine the chemical composition of materials. It works by exposing a material to a source of X-rays or gamma rays, which causes the material to emit fluorescent (or secondary) X-rays. These secondary X-rays have energies characteristic of the elements present in the material, allowing for a precise identification and quantification of these elements.
