SIRFER Home


The Stable Isotope Ratio Facility for Environmental Research (SIRFER) is a research and recharge facility within the Biolog Department at the University of Utah. This isotope ratio mass spectrometer facility serves research and teaching needs for stable isotope ratio analyses within the Biology Department and other departments on campus. The focus of SIRFER is on studies in which stable isotope analyses are a key element for interpreting information on enviornmental reconstruction, ecosystem processes, plant-animal interactions, and sourcing or geo-location determination. Additionally, SIRFER has provided stable isotope analyses for more than 200 laboratories at different universities and research institutions across the United States and around the world in the past ten years and will continue to provide such services in the future.
