A monochromator is a component installed in front of an X-ray detector, which monochromatizes the X-rays passing through a receiving slit and only detects K α characteristic X-rays in the X-ray spectrum. By using this device, continuous X-rays, K β characteristic X-rays, and fluorescent X-rays can be completely eliminated, enabling high signal-to-noise ratio X-ray diffraction analysis. When copper target X-ray tubes are used in conjunction with corresponding monochromators, fluorescent X-rays generated from Mn, Fe, Co, Ni based samples can be eliminated, making them suitable for analysis of various samples.

The use of graphite bent crystal monochromator can improve the peak to background ratio, reduce the background, enhance the resolution of weak peaks, achieve a reflection efficiency of n ≥ 35%, and reduce the diffraction angle of the diffractometer. Embedding degree ≤ 0.55; The crystal surface can tilt ± 2 degrees.
