Unit 7, Trinity Technology And Enterprise Centre (TTEC), Pearce Street.

Instrument

Bruker D5000 powder has a 2.2 kW Cu long fine focus (0.4 x 12mm filament) a scintillation counter detector, and configurable optics (standard configuration: 2.5° primary soller, 1 mm aperture diaphragm, 1 mm scattered radiation diaphragm, no secondary soller, 0.2 mm detector diaphragm and a secondary curved graphite monochromator).

Samples

Powdered samples, typically 0.6 – 1.0 g. Can run smaller samples and <2 μm clay extracts.

Additional information

Bruker Diffrac.EVA software is used for peak-matching to database lines in the current International Centre for Diffraction Data, Pennsylvania, PDF-4 3+ database. The semi-quantitative analysis is performed using Sietronics Siroquant software (Version 4.0, Release 5, with database v3.0g). Radiation Safety Training is required before use.
