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.

The high-precision multifunctional angle measuring instrument of Tongda Technology can not only measure conventional powder samples, but also test liquid samples, colloidal samples, viscous samples, loose powders, and large solid samples.

X-ray diffraction is the most effective and most widely used means, and X-ray diffraction is the first method used by humans to study the microstructure of matter.
