CURRENTLY OPERATIONAL INSTRUMENTS
1) D8 ADVANCE Bruker powder diffractometer (theta/2 theta)
equipped with a monochromator and a solid state detector.
This is our principal powder diffractometer. It is equipped with a Ge monochromator and a SOL-XE solid state detector and has a resolution of 0.001°. It is also equipped with an automatic sample changer which can accomodate 9 sample.
It is suitable for highly accurate lattice parameters and size and strain determination with top-quality measurements (which has no equal in the other X-ray labs of the University), and for Rietveld refinement for structural and quantitative analysis, as well as for routine analysis for identification purposes.
This instrument has higher resolution than any equivalent diffractometer in the University.
2) D8 ADVANCE Bruker powder diffractometer (theta/theta)
equipped with Goebel Mirror for parallel beam with a VANTEC-1 fast detector
With two possible sample stages:
i) MIR heating stage: this allows in-situ high temperature collections up to 1400C with top-quality measurements, which has no equal in the whole University X-ray labs.
ii) Capillary stage: used for air-sensitive samples or for accurate intensity measurements suitable for better structural and quantitative analysis.
No other diffractometer in the University allows data collection under such extreme conditions. The ability to operate at high temperature allows users to approach research questions that would otherwise not be possible. It has a resolution of 0.001°
3) Bruker D5000
This powder diffractometer has a Siemens goniometer platform with a resolution of 0.01° and a 40 sample automatic sample changer. It is primarily used for clay mineral studies and routine mineral/phase identification.
We also have computer access to a number of softwares and databases.
