Welcome to the Stable Isotope Facility

The Stable Isotope Facility (SIF) offers analysis for stable isotopes of several light elements (H,C,N,O) in a wide variety of sample forms at natural abundance or tracer levels. Most samples can be efficiently analyzed by continuous flow Isotope Ratio Mass Spectrometer (IRMS). A dual inlet IRMS is available for very high precision work. The following analyses are available:

• Solid samples for combustion, soils, plant materials, dried extracts etc. (C,N)
• Solid samples for ‘pyrolysis’, organic materials, salts (H,O)
• Atmospheric gases, (N2, O2, CO2, CH4, N2O)
• Compound specific isotope analysis of fatty acid methyl esters (FAMEs) using GC-C-IRMS
• Water (H2, O2) enriched or small samples
• Dissolved inorganic and organic carbon (water or extracts)

Located on the University of California, Davis campus, the SIF provides analytical services for local, national, and international researchers. We analyze over 125,000 samples every year on 11 analytical systems.
