The TD-5000 X-ray Single-Crystal Diffractometer is a high-performance instrument developed by Dandong Tongda Technology. Approved under China's National Key Scientific Instrument and Equipment Development Project, it fills a critical domestic gap in this field. Its primary function is determining the three-dimensional spatial structure and electron density distribution of crystalline substances—including inorganic compounds, organic compounds, and metal complexes—while also analyzing structures of special materials like twinned crystals, incommensurately modulated structures, and quasicrystals. It precisely measures the accurate 3D spatial structure of new crystalline compounds (including bond lengths, bond angles, configuration, conformation, and bonding electron density) and the actual arrangement of molecules within the crystal lattice. The system provides comprehensive structural information such as unit cell parameters, space group, molecular structure, intermolecular hydrogen bonding and weak interactions, and molecular configuration/conformation. It is widely used for analytical research in chemical crystallography, molecular biology, pharmacology, mineralogy, and materials science.
