X-Ray Diffraction

X-ray powder diffraction (XRD), is an instrumental technique that is used to identify minerals and other crystalline materials. XRE provides data used to determine the rock composition in regard to mineral present, clay mixtures or intergrowths of minerals that may not be identified by other methods..  XRD values are used determine and calibrate mineral volume calculations derived from well log data.

XRD is based on the scattering of X-rays from atoms that produce a diffraction pattern, which contains information about the atomic arrangement within the sample. The technique is based on Bragg’s Law. It is more a qualitative analysis by determining the relative amount of phase differentials in a substance by referencing relative peak intensities.

Rigaku MiniFlex 600

The fifth generation MiniFlex is a general purpose X-ray diffractometer that can perform qualitative and quantitative analysis of polycrystalline materials. 

Ideally-suited for today’s fast-paced XRD analyses, the new 5th generation MiniFlex delivers speed and sensitivity through innovative technology enhancements such as the optional D/teX high speed detector coupled with the new 600 W X-ray source.
