WebMay 5, 2024 · How Does X-Ray Fluorescence Work? X-ray fluorescence is reliant on the ionization process, whereby an atom will gain a positive or negative charge as it loses or gains electrons to create ions. Exposure to short wavelength X-ray beams and gamma rays can cause atoms inside a material to ionize. 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.
