X-Ray Diffraction (XRD)
X-ray diffraction (XRD) is a technique used to identify crystalline phases in solid samples. The samples are usually crushed to randomly orientate the grains in order that all of the crystallographic "faces" of the crystals present are available for analysis.
Siemens D5000 X-ray Diffractometer
A Siemens D5000 Diffractometer (XRD) theta-2 theta goniometer with a copper
anode x-ray tube, fixed slits , monochromator and a forty position sample
changer allows phase & mineral identification. DiffracPlus with the search/match
option is used to collect and analyse the diffraction data. Quantitative XRD
Analysis is performed using either DQUANT or SIROQUANT dependent on the material
and standards available.
Bruker-AXS Smart 1000 CCD Single Crystal Diffraction
A Bruker-AXS Smart 1000 CCD is used to determine the structure of single crystals and is primarily a research instrument for the university. The use of CCD technology has reduced the time to collect data from days to hours. Software used includes SHELXTL, XSCANS, ASTRO & Saint.
X-Ray Fluorescence (XRF)
X-ray fluorescence (XRF) is a technique employed to determine the major (wt%) and trace (ppm) levels of in-organic elements present in solid samples (their chemistry). The samples are crushed and then either compressed into a disk or fused to form a glass-like bead.
Bruker-AXS S4 Pioneer X-ray Fluorescence Spectrometer
A Bruker-AXS S4 Pioneer X-ray Fluorescence Spectrometer (XRF) with 108 position sample changer allows elemental analysis on solid (B - U) and (Na - U) for liquid samples. SpectraPlus software is used to operate the spectrometer. Analysis of geological and vegetation samples are routinely performed. Semi-quantitative analysis using SpectraPlus provides quick results to survey materials or resolve process problems. The centre can also provide analysis using your standards for other materials. No standards, the elemental spectroscopy unit can analyse a wide range of materials to provide internal standards for calibrations or produce synthetic standards from pure chemicals. Sample preparation equipment used includes fusion furnace , Rocklab ring mills and Boyd crusher
