Microanalysis and Microscopy: Capabilities

X-Ray Diffraction Analysis

The XRD is used for determining the crystalline structure of anything from minerals to pharmaceuticals. Each substance has a unique way of reflecting X-rays that are beamed at it, and the resultant diffraction pattern can be used to identify unknown substances and combinations of substances in one sample. Libraries of expected responses in the form of spectra are used to compare known responses of standard materials to the results from the unknown substance. RTI’s library database has information on over a quarter million known inorganic and organic substances, and a computerized program to match spectra. This powerful database allows for a myriad of search parameters to be chosen in combinations customizable by the user to determine the identity of unknown materials. The XRD is generally capable of documenting the presence of any component present in the sample at greater than 1%.
