Background

EDXRF generally refers to polarization-excited X-ray fluorescence spectroscopy, and laboratory-type polarization-excited EDXRF spectroscopic analysis technology is a new multi-element primary, secondary, and trace element analysis technology developed in the 20 th century. It generally employs an X-ray tube source and a semiconductor detector. The X-ray generated by the X-ray tube is polarized by the polarizing target and then irradiated on the sample as an excitation light source. Three axes formed by connecting the sample and the detector, the polarizing target and the sample, and the X-ray tube and the polarizing target are respectively positioned on the X-axis, the y-axis and the z-axis of a Cartesian coordinate system on the structure of the instrument. The geometric construction can greatly reduce the detection background caused by elastic and inelastic scattered X photons, thereby improving the signal/back ratio and reducing the detection limit. Meanwhile, the polarization excitation source also has a certain selective excitation effect. Its outstanding advantage is the quick analysis ability of primary, secondary and trace elements, and can analyze all elements from Na to U.
