D8 DISCOVER with PILATUS

X-ray diffraction is unique in its ability to identify and quantify the structural phases present in a sample; this is in contrast to the elemental constituents identified with many other techniques.

When analyzing geological samples, sensitivity to the structure of various phases is exceptionally important as many phases have the same elemental building blocks, differing only in the way that those blocks are arranged. Frequently, it is advantageous to leave the sample in an as-collected state, rather than reducing it to a powder in a ball mill, to allow further petrographic analysis.

Two dimensional detectors are uniquely suited for this analysis as the large diffraction space coverage can capture reflections from crystallographic phases with large grain sizes and preferred orientations that would otherwise be missed.
