X-ray diffraction – an atomic view into your material

Which polymorphs are present in my sample? What is the relative distribution of minerals in a geological sample? How big are the particles in a nanomaterial? 

At the Danish Technological Institute we offer analysis on a state-of-the-art X-ray diffractometer. Powder X-ray diffraction provides a wealth of information about your material. The analytical technique is useful in quality control of pharmaceutical powders, investigation of polymorph structures, and identification of impurities in a material. For other industries, analysis of mineral composition or size determination of nanomaterials may be the key information needed to understand problems in processing or development of products.

A classic example of the use of PXRD is to determine polymorphism of a substance. Polymorphism is the propensity of a substance to crystallize into more than one crystal structure. As different polymorphic forms will have different properties, this is of extreme importance in pharmaceutical materials.

Our services include powder diffraction and small angle X-ray scattering analysis for chemistry, material science, and pharmaceutical companies. Our experienced diffraction specialist and multipurpose diffractometer will help provide the knowledge that your company needs.
