X-ray diffractometry in pharmaceutical analysis: practices of using "Difray" benchtop diffractometers

Limits of applicability of the XRD-analysis for control of pharmaceutical production and intermediate products compliance with the factory regulations and for monitoring of mechanocomposite formation with the changed reactionary ability are shown. XRD-analysis allows you to investigated solid-phase reactions, polymorphism, changes of biological activity of substances and medical products. Possibilities of the XRD-analysis are illustrated by the experimental data received by means of desktop X-ray diffractometer "Difray" produced in Russia Federation.
