The PANalytical X'pert MPD X-ray Diffractometer is used extensively in our Forensic Geosciences course. It has the following basic configuration and capabilities:
Theta-theta configuration with operational range of 0-167° 2-theta (this means that the sample stage is fixed while the X-ray source and detector rotate around it).
Copper (Cu) High Power tube – line or point focus
X’Celerator High Speed Detector system
Graphite monochromomator (for suppressing fluorescence)
Focusing Beam(powders and flat samples) and Parallel Beam optics (thin films and irregularly shaped samples).
Sealed Xe Proportional Detector for use with Parallel Beam optics
Fixed divergence and anti-scatter slits from 1/4 - 2 degree.
Multiple sample stages – 15 position sample changer for powder samples, Flat sample mount sample stage, and multipurpose stage capable of supporting 10cm x 10cm x 10cm samples up to 1kg.
Data collection and analysis software
On-line sample identification with ICDD database and access to PDF-2 database
