X-ray Fluorescence

X-ray fluorescence is a physical phenomenon that is based on the phenomenon that when an atom is irradiated with electromagnetic radiation, typically energy of the KeV order, it is able to absorb an incident photon and expel an electron from the more internal shells (Photoelectron). The rearrangement of the remaining electrons between the various levels of the atom involves the emission of a photon X whose energy is characteristic of the emitter atom.

The physical phenomenon of fluorescence X is exploited by modern spectrometers for qualitative and quantitative determinations on samples of various nature. For quantitative spectral analysis, what is used is the so-called "fundamental parameter method", a numerical calculation algorithm that, from the theoretical knowledge of the physical fluorescence process, allows to obtain quantitative data on sample composition.
