Multicollector mass spectrometer for isotopes
Commissioned in early 2008, this facility consists of a Nu Instruments TM multi-collector ICPMS equipped with a deep UV excimer laser model G2, built by Photon Machines TM, for analysis of isotopic systems in solids. The instrument also has a desolvating nebulizer, for analysis of isotopes in liquids.
Methodologies in use include:
- Age dating – in situ U-Pb
- Zircon, monazite, titanite, xenotime
- Sulfur & copper isotopes – in situ on sulfides
- Li, Mg, Sr, Pb, U – on waters and single element solutions
- Sr isotopes – in situ on plagioclase
- Pb isotopes – in situ on K-spar, sulfides, tellurides
- Hf isotopes – in situ on zircon
- U series – on single element solutions
