en.wikipedia.org The impurities measured are at the atomic level within the crystal lattice of carbon atoms and so, unlike inclusions, require an infrared spectrometer to detect.
en.wikipedia.org When the ions pass through the mass analyzer of the spectrometer, they strike the scintillator compound and cause the release of photons.
