Measuring principle

 X-rays are used to expel tightly held electrons from the inner orbitals of the atom. The removal of an electron in this way makes the electronic structure of the atom unstable, and electrons in higher orbitals ‘fall’ into the lower orbital to fill the hole left behind. Each of these transitions yields a fluorescent photon with a characteristic radiation equal to the difference in energy of the initial and final orbital. The fluorescent radiation is then analyzed by separating the characteristic wavelengths (qualitative) and detecting intensity of each characteristic radiation (quantitive).
