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 divided into two kinds of single crystal diffraction and powder diffraction, single crystal is mainly used for the determination of molecular weight and crystal structure, powder is mainly used for the identification and purity of crystalline substances.

Global X-ray diffractometer (XRD) has developed steadily in recent years, and China is a market with great development prospects.

Dandong Tongda Technology Co., Ltd. has not only made great achievements in the performance and configuration of the machine, but also a complete after-sales service system to give users a perfect experience.
