X-ray diffraction

ARL Thermo X'tra

The X-ray diffraction lab is equipped with an ARL Thermo X'tra powder diffractometer. The instrument enables the characterization of materials based on the diffraction of X-rays as they go through the lattice of the crystal. This diffractometer features X-ray optics on the goniometer to provide resolution in the low angle region where peaks can be observed down to 0.5°. The instrument is also equipped with a Peltier-cooled Si(Li) solid state detector.

Analyses of major minerals are made on powder samples, whereas for clay minerals oriented preparations are needed.
