The UW Stable Isotope Facility is a core research lab at the University of Wyoming. The UW SIF provides quality isotopic analyses for the research community at UW and other universities/ labs nation-wide. UW SIF is a hands-on teaching and research facility for UW students, postdocs and faculty. We are engaged in development of novel analytical techniques for research in biological and earth system sciences. 

The facility is equipped with two Finnigan Delta+XP continuous flow inlet Stable Isotope Ratio Mass Spectrometers (IRMS). We also have a Micromass Optima Dual Inlet IRMS, and a Micromass IsoPrime continuous flow IRMS. All instruments are configured for the analysis of H, C, N, and O. These mass-spectrometers are connected to eight different peripheral devices, helping to meet the growing demands of researchers and students on campus. We have recently acquired a laser based Liquid Water Isotope Analyzer from Los Gatos Research for measurement of H and O of waters.  The laboratory also has vacuum extraction lines for off-line preparation and purification of sample gases.
