We have the following major instrumentation in the geochemistry group:
- Nu Instruments MC-ICP-MS, used for isotope analysis of Mg, Ca, Sr, Ge, Nd, U, Th, Pb, and other isotope systems
- Perkin Elmer Elan DRC II ICP-MS "the quad" - analyses a wide range of samples for trace element concentrations. We routinely run silicate rocks, plants, and foraminifera and can handle many different environmental sample types
- Varian Vista-PRO Simultaneous ICP-AES, mostly used for foraminfera analysis (Element /Ca ratios) but also for major and minor element concentrations in a wide variety of sample types
- New Wave UP213 Laser Ablation system, usually interfaced to the Elan but can be also interfaced to the other ICP instruments
- VG Sector 54 TIMS (multicollector thermal ionisation mass spectrometer) used for isotopic analyses of Sr, Nd, Ra, and U/Th
These instruments are backed up by extensive laboratory facilities for sample preparation including several clean trace metal laboratories. In addition, the Godwin Laboratory operates multiple gas source stable isotope mass spectrometers.
The Department is exceptionally well-equipped to undertake chemical analysis related to problems including climate change, hydrothermal activity on mid ocean ridges, petrology and palaeoceanography.
