XRD is a nondestructive analytical technique used to identify (and quantify) minerals in samples. We measure random powder mounts and oriented clay mounts. Sample preparation is more important than the settings of the X-ray diffractometer in determining the quality of the results. If you want to do analysis on our XRD, please be sure to contact the technical experts before grinding your samples. Depending on your research goal, we can advise you whether and how your samples should be milled.

The Particle Size Analyzer uses the technique of laser diffraction to measure the grain size distribution of loose grains. It does this by measuring the intensity of light scattered as a laser beam passes through a sample of dispersed grains within the range of 0.02–2,000 μm. The grain size distribution of a sample can be determined on bulk samples or on insoluble residues after chemical pretreatments (carbonate-free and/or biogenic silica-free residues). If a sample is cemented, then the cement needs to be removed chemically, but this is not always possible (e.g. quartz cements). Organic matter may also be removed.
