MES offers rapid and reliable X-Ray Diffraction analysis.


x-ray diffraction (xrd)

Our expert chemists can assist you with X-ray diffraction (XRD) for characterizing your crystalline materials. XRD is a non-destructive technique used for the identification of a crystalline phase or mineral. However, it can also provide information on structures, preferred crystal orientation, and other structural parameters, such as average grain size and strain distribution.

X-ray diffraction patterns are produced by a goniometer, which is rotated at specific angles while bombarding the sample material with X-rays. The diffraction pattern peak intensities are determined by the distribution of atoms within the lattice. The x-ray diffraction pattern is specific to the periodic atomic arrangements in a given material, which is compared to the ICDD standard database of x-ray diffraction patterns for phase identification.
