Our research group operates three HEPA-filtered clean rooms, one for routine chemistry, the second predominantly an instrument lab, and a third dedicated to low level U-Th-Pb geochronology, primarily for speleothems. Chemical separation and mass spectrometry procedures have been established for the isotopic analysis of many elements of interest e.g., Cu, Zn, Rb-Sr, Sm-Nd, Lu-Hf, and U-Th-Pb. In addition, full trace element characterisation is performed by quad ICPMS, with either bulk or in situ sampling by laser ablation.
The core analytical instrumentation comprises two Nu Plasma MC-ICPMS (Nu Instruments, U.K) and an Agilent 7700 quadrupole ICPMS. One of the MC-ICPs and the quad-ICP are coupled to deep UV 193nm excimer laser ablation systems. Arriving soon we have a Nu Attom double-focussing ICPMS which will also be connected to a UV laser ablation probe.
As members of the School of Earth Sciences researchers also have access to a wide range of other instrumentation and techniques including XRF, SEM, electron probe, Ar-Ar geochronology, noble gases, cosmogenic isotopes, U-Th-He thermochronology, fission track thermochronology, and supercomputing, together with extensive stable isotope mass spectrometry facilities run by our colleague, A/Prof Russell Drysdale in the Department of Geography.
