Welcome to the Stable Isotope Facility

      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 researchers world-wide. UW SIF offers 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. Our mission is to provide quality data with the utmost integrity. Interpretation of this data is left up to the user.

      The Stable Isotope Facility is located in the Berry Biodiversity Conservation Center, in a laboratory designed specifically for an isotope facility.  The facility is equipped with two Finnigan Delta+XP and a Delta V continuous flow inlet Stable Isotope Ratio Mass Spectrometers (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. A laser based Liquid Water Isotope Analyzer from Los Gatos Research and a Picarro analyzer are used for isotopic  measurements of H and O of waters.  The laboratory provides many sample prep devices including vacuum extraction lines, micro balances, ovens, centrifuge, freeze dryer, and grinders for users on campus.  The newest additions to the facility are a GC in-line with a quadrupole mass spec and a GC-C isotope ratio mass spectrometer(Delta V) for exploring compound specific work.  This instrumentation is available to qualified University of Wyoming researchers.  UWSIF DOES NOT perform compound specific analyses. 


To submit samples please follow the directions on the Sample Submission page.

UW’s Stable Isotope Facility Expands Lab Analysis to Plant Samples

August 30, 2016 — For the past two years, the University of Wyoming’s Stable Isotope Facility (SIF) has been the go-to laboratory to analyze National Ecological Observatory Network (NEON) soil samples from all across the country. Based on that solid soil work, the facility has added plant samples to its research list.
