1. Function of single crystal diffractometer:
The TD-5000 X-ray single crystal diffractometer is mainly used to determine the three-dimensional spatial structure and electron cloud density of crystalline substances such as inorganic, organic, and metal complexes, and to analyze the structure of special materials such as twinning, non commensurate crystals, quasicrystals, etc. Determine the accurate three-dimensional space (including bond length, bond angle, configuration, conformation, and even bonding electron density) of new compound (crystalline) molecules and the actual arrangement of molecules in the lattice; X-ray single crystal diffractometer can provide information on the crystal cell parameters, space group, crystal molecular structure, intermolecular hydrogen bonding and weak interactions, as well as structural information such as molecular configuration and conformation.X-ray single crystal diffractometer is widely used in analytical research in chemical crystallography, molecular biology, pharmacology, mineralogy, and materials science.
The X-ray single crystal diffractometer is a high-tech product funded by the Ministry of Science and Technology of China's National Major Scientific Instrument and Equipment Development Project, led by Dandong Tongda Technology Co., Ltd., filling the gap in the development and production of single crystal diffractometers in China.

4. Angle measuring instrument used in single crystal diffractometer:
The use of four concentric circles technique ensures that the center of the angle measuring instrument remains unchanged regardless of any rotation, achieving the goal of obtaining the most accurate data and obtaining higher completeness. Four concentric circles are a necessary condition for conventional single crystal diffractometer scanning.
5. High speed two-dimensional detector used in X-ray single crystal diffractometer:
The detector combines the key technologies of single photon counting and mixed pixel technology to achieve the best data quality while ensuring low power consumption and low cooling. It is applied in various fields such as synchrotron radiation and conventional laboratory light sources, effectively eliminating the interference of readout noise and dark current. The mixed pixel technology can directly detect X-rays, make the signal easier to distinguish, and efficiently provide high-quality data.
