Review:
X Ray Fluorescence (xrf) Spectroscopy
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
X-ray fluorescence (XRF) spectroscopy is a non-destructive analytical technique used to determine the elemental composition of a wide range of materials. It works by exposing a sample to primary X-rays, which excite the atoms within the material, causing them to emit secondary (fluorescent) X-rays at characteristic energies. By analyzing these emitted X-rays, it is possible to identify and quantify the elements present in the sample with high accuracy and speed.
