The TD-3700 high-resolution X-ray diffractometer is equipped with a variety of high-performance detectors such as high-speed one-dimensional array detectors, two-dimensional detectors, SDD detectors, etc. TD-3700 X-ray diffractometer integrates fast analysis, convenient operation, and user safety. The modular hardware architecture and customized software system achieve a perfect combination, making its failure rate extremely low, anti-interference performance good, and ensuring long-term stable operation of high-voltage power supply. TD-3700 X-ray diffractometer can increase the diffraction calculation intensity by tens of times or more, obtain complete high-sensitivity, high-resolution diffraction patterns and higher counting intensity in a shorter sampling period, and also support transmission data scanning. 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.
