X-ray diffractometer is mainly used for phase qualitative and quantitative analysis, crystal structure analysis, material structure analysis, crystal orientation analysis, macroscopic or microscopic stress determination, grain size determination, crystallinity determination, etc. of powder, block or film samples. The TD-3500 X-ray diffractometer produced by Dandong Tongda Technology Co., Ltd. adopts imported Siemens PLC control, which makes the TD-3500 X-ray diffractometer have the characteristics of high accuracy, high precision, good stability, long service life, easy upgrade, easy operation and intelligence, and can flexibly adapt to testing analysis and research in various industries! It is a powerful analytical tool widely used in fields such as materials science, chemistry, physics, and geology.

X-ray diffraction is a basic technique for the study of solid structure, which can provide unique spectral information for the chemical composition and structure arrangement of samples.

Different crystal forms of the same drug may differ significantly in appearance, solubility, melting point, etc., affecting the stability, production, bioavailability, and safety of the drug.

Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of not destroying samples and simple operation, and is the main method for the qualitative and quantitative analysis of drug polymorphism at present.
