Micro X-ray diffraction analysis on a meteorite

Microspot analyses and phase distribution mapping on a carbonaceous chondrite

In this study a slice of the Northwest-Africa 2086 meteorite was subject to micro X-ray diffraction (XRD) investigations. NWA 2086 was found in 2003 with a total known weight of 780 g.

The use of the focusing X-ray lens in combination with positioning stages and sample alignment tools allows us to perform precise microspot analyses with a spatial resolution as high as 50 μm without compromising in intensity. In addition it allows us to perform phase distribution mapping revealing mineralogical differences in heterogeneous samples.
