Welcome!
Located in the Stephenson Research and Technology Center on the University of Oklahoma Norman campus, the Stable Isotope Measurement Facility (SIMF) provides analytical services to researchers in a variety of disciplines. SIMF offers analyses of carbon and nitrogen isotopes via continuous-flow isotope ratio mass spectrometry and cavity ring-down spectroscopy. Our facility seeks to further innovative research at OU and serve the broader research community through hands-on training and fostering collaboration between students, post-doctoral associates, faculty, and visiting scholars. The following are the current services that we provide:
• C and N in solid, organic materials such as plants and soils including both natural abundance and enrichment/tracer studies
• Carbon isotope analysis of CH4 and CO2
