This lab contains two isotope ratio mass spectrometers:

(1) A GV Instruments (Micromass) IsoPrimeTM mass spectrometer with universal triple collector and additional H/D assembly. The instrument is equipped with dual inlet and high throughput continuous flow modes. The system includes a Multi-PrepTM inlet module and Gilson autosampler for high precision determinations of carbonate δ18O and δ13C and water sample δ18O and D/H ratios.

(2) A GV Instruments IsoPrimeTM Continuous Flow Isotope Ratio Mass Spectrometer with universal triple collector. Peripherals include a Gilson GX271 autosampler and a Trace Gas system for cryogenic trapping of low concentration atmospheric gases, such as N2O, CH4, and CO2. This system includes a EuroVector high temperature elemental analyzer for combustion or pyrolysis sample preparation and determination of elemental and isotopic ratios (C, H, N, and S) of sediments, soils, and biological materials. The EuroVector system includes a diluter kit for sequential carbon and nitrogen isotope analysis and a liquid autosampler for the analysis of H/D through chrome reduction techniques.
