This article details a comprehensive three-pronged strategy to eliminate higher-order diffraction interference in X-ray single-crystal analysis. The methods involve hardware filtration at the source using monochromators and slits, parameter optimization during data collection to suppress detection, and software correction algorithms for residual effects in data processing. This combined approach ensures high-precision crystal structure determination by controlling intensity errors.

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; It 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. Single crystal XRD is a high-tech product under the National Major Scientific Instrument and Equipment Development Project of the Ministry of Science and Technology, led by Dandong Tongda Technology Co., Ltd., filling the gap in the development and production of single crystal x-ray diffractometer in China.
