X-Ray Diffraction Lab (XRD)

XRD is used to identify and characterize crystal phases in powdered samples. Minerals and synthetic crystals produce characteristic x-ray patterns that can be compared with a database of known phases using analytical software. The department has a PANalytical X’Pert Pro diffractometer equipped with a Co x-ray tube and the very fast X’Celerator detector. The unit has a 15 position sample changer and a set of low background sample holders for samples as small as 1 milligram.
