Background

The metal spectrum analyzer is an instrument for rapidly detecting the components of a metal material groove by adopting an XRF (X-ray fluorescence spectrum analysis) principle. X-ray fluorescence analysis is a method for determining the types and contents of trace elements in substances, also called X-ray secondary emission spectroscopy, and is a method for performing substance composition analysis and chemical state research by exciting atoms in a substance to be tested by primary X-ray photons or other microscopic particles to generate secondary characteristic X-rays (X-ray fluorescence). X-rays are invisible light having a very short wavelength, but when it is irradiated to some compounds such as phosphorus, platinum barium cyanide, zinc cadmium sulfide, calcium tungstate, etc., atoms are in an excited state due to ionization or excitation, and during the return of the atoms to a ground state, visible light or ultraviolet rays are radiated due to energy level transition of valence electrons, which is fluorescence.
