WebIntroduction. X-ray fluorescence (XRF) spectrometry is an elemental analysis technique with broad application in science and industry. XRF is based on the principle that individual atoms, when excited by an external energy source, emit X-ray photons of a characteristic energy or wavelength. WebAs an X-RAY XRF device starts a measurement, the X-ray tube emits high-energy radiation, which is also called the ‘primary’ radiation. When these X-rays hit an atom in the sample, they add energy – i. e. they ‘excite’ it – causing the atom to eject an electron close to its nucleus, a process known as ‘ionization’. how fast night changes
