X-Ray Diffraction (XRD) uses the "fingerprint" of a crystalline material to allow identification of unknown phases in a mixture. It is commonly used in the engineering, geological and materials sciences for applications such as corrosion studies, material fabrication, analysis of combustion products, mineral identification and determination of lattice parameters.
Rapid identification of unknowns is possible using search/match software available at the unit and quantification of the various phases is also possible in some cases.
Samples may be in solid or powder form, and the technique is non-destructive . Sample changers are available on both XRDs for unattended analysis of powder samples.
The Xpert XRD has a heating stage for analysis up to 1600ºC.
