The TD-3700 high-resolution X-ray diffractometer, with all the advantages of the TD-3500 X-ray diffractometer, is equipped with a high-performance array detector. Compared to scintillation detectors or proportional detectors, diffraction calculation intensity can be increased by several tens of times, and complete high-sensitivity, high-resolution diffraction patterns and higher counting intensity can be obtained in a shorter sampling period. The TD-3700 high-resolution X-ray diffractometer supports both conventional diffraction data scanning and transmission data scanning methods. The resolution of transmission mode is much higher than that of diffraction mode, which is suitable for structural analysis and other fields. Diffraction mode has strong diffraction signals and is more suitable for routine phase identification in the laboratory. In addition, in the transmission mode, the powder sample can be in trace amounts, which is suitable for data acquisition in cases where the sample size is relatively small and does not meet the requirements of diffraction method for sample preparation.

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.
