 XRD - Bruker D8 |
Overview
Installed in 2008, the Bruker D8 Advance provides routine, non-quantitative mineral
identification in rock powders. The D8 XRD is now driven by automation software with integrated pattern analysis by Bruker EVA and Topas using the ICDD PDF-2 Minerals
database.
Samples
Samples for XRD must be carefully ground rock powders (no gritty lumps) or fine
size fractions separated by centrifugation or gravity settling. Ideally, the
mineral phases of interest should be present in amounts of at least several
percent. Otherwise, some method of concentrating the phase will be necessary.
