Powder X-ray diffraction, as one of the methods for the study of drug polymorphism, has the advantages of no sample destruction and simple operation.

SBA-15 is a mesoporous silicon-based molecular sieve with a highly ordered hexagonal straight pore structure (p6mm), the pore size can vary from 5 to 50 nm, and the pore wall is thicker.

The X-ray transmission inspection can provide a picture of whether there are defects in the inspection site of the casting and the relevant size, and the X-ray inspection system is widely used in industrial production.

In the past 10 years, the Institute of Physics of the Chinese Academy of Sciences has used powder diffraction method to determine the crystal structure of many inorganic and organic compounds.

X-ray detector is a device used to detect X-rays, which has a wide range of applications in medicine, science and industry. X-ray detectors convert X-rays into electrical signals for digital processing and imaging.

X-rays have a short wavelength and high energy, and can penetrate objects to directly observe internal defects. Highly praised in the field of non-destructive testing. In fact, there is another function that is also widely used, namely foreign body detection.

Nondestructive testing (NDT) is a kind of testing method widely used in various industries, which is widely praised for its high precision, high resolution imaging effect and fast and efficient detection speed.

SBA-15 is a kind of mesoporous molecular sieve, and its synthesis is another important chemical technology emerging in recent years.

Nowadays, X-ray imaging technology has formed a relatively complete X-ray non-destructive testing technology system. New detection technologies are also being innovated, using Xray online detection technology.

Grazing incidence means that the X-ray is exposed to the film at a very small incidence Angle (< 5°), which greatly reduces the penetration depth in the film.At the same time, the low incidence Angle increases the irradiation area of the X-ray on the sample

Parallel beam XRD of X-ray optical crystals has been successfully applied in thin film analysis, sample texture evaluation, crystal phase and structure monitoring, etc.
