The Department of Geology and Planetary Sciences at the University of Pittsburgh is equipped with a dedicated stable isotope laboratory facility.  This facility houses two GV Instruments, Ltd. (now Isoprime, Ltd., a subsidiary of Elementar Analysensysteme) Isoprime™ stable isotope ratio mass spectrometers with universal triple collectors and additional H/D assemblies.  One instrument is equipped with both traditional dual inlet and high throughput continuous flow modes. This system includes a Multi-Prep™ inlet module and Gilson autosampler for high precision determinations of carbonate δ¹⁸O and δ¹³C and water sample δ¹⁸O and D/H ratios. The second instrument is a dedicated continuous flow isotope ratio mass spectrometer equipped with a Gilson GX271 autosampler and a TraceGas™ inlet system for cryogenic trapping of low concentration atmospheric gases. In addition, the laboratory is equipped with 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.
