The three-dimensional space of atoms is arranged in a long-range order, and the smallest unit of repeated arrangement is called the cell, which can be divided into 7 kinds of crystal systems, 14 kinds of lattice, and 230 kinds of space groups according to the arrangement law.

The main indicators of polymer materials include the type of polymer or its crystallinity. Polymers also exhibit different microstructure, which can also affect the mechanical .properties of polymer materials.

X-ray diffraction (XRD) is a means of research to obtain information such as the composition of a material, the structure or form of an internal atom or molecule by analyzing its diffraction pattern through X-ray diffraction.

Dandong Tongda TD-5000X-ray single crystal diffractometer won the "ACCSI2023 Instrument and Detection 3i Award --2022 Annual Scientific Instrument Industry Outstanding New Product Award".

It is a professional manufacturer of X-ray analysis instruments and non-destructive testing instruments, and has obtained a number of certifications such as national high-tech enterprises, ISO quality system certification enterprises, and has an invention patent and utility model patent.

Crystals, although long admired for their regularity and symmetry, were not studied scientifically until the 17th century. Let's take a look at the early history of crystallography.

X-ray diffractometer (XRD) is the use of diffraction principle, accurate phase analysis, qualitative analysis and so on. Today, we will introduce some accessories that can be equipped with XRD instruments.
