To determine whether there is asbestos in talc is usually a combination of polarizing or electron microscopy and X-ray diffraction, and the quantitative analysis of asbestos mainly uses X-ray diffraction method.

Small Angle X-ray scattering (SAXS) is a technology that collects scattered signals generated by X-rays passing through a sample to study the structural information of a sample in the range of 1~100 nm.

Most drugs exist in the form of crystals, using X-ray diffraction, we can obtain the diffraction information of drug characteristics for each different crystal type.

The Guiding Principle of Chiral Innovative drugs clearly stipulates that "the direct method for determination of molecular configuration of chiral drugs is single crystal X-ray structure analysis".

X-ray diffraction is an important means for people to understand and explore nature, especially in condensed matter physics, life medicine, history and many other fields play an active role.

Unlike powder XRD, which is widely used in the late stage of drug development and production, single crystal X-ray diffraction technology plays an important role in the early and middle stages of drug development.

Dandong Tongda Technology Co., LTD., with professional technology and perfect service, has won the trust of scientific research workers around the world.

With the gradual increase of drug crystal regulation, the quantitative analysis of the effective crystal in drug preparations is a very important link in the quality control process of drug production.

XRD technology is widely used in the fields of crystallography, physics and metallurgy, including qualitative and quantitative, crystal structure, mechanical analysis, etc. This paper mainly lists its application in polymer research.

The application of XRD in the refractory industry involves all aspects of refractory production. From raw material quality inspection, production process control to product quality inspection.
