The University of Michigan Stable Isotope Laboratory is located in the Department of Geological Sciences.  The laboratory provides analytical support for researchers both university-wide and from universities and facilities around the world.  We specialize in the preparation and analysis of light stable isotopes (Hydrogen,Carbon, and Oxygen).

• Finnigan MAT 251 triple-collector gas source mass spectrometer coupled to a Finnigan Kiel automated preparation device.  This device is dedicated to the analysis of carbonates and has the capability to analyze samples as small as 10 micrograms.
• Finnigan MAT Delta S triple-collector gas source mass spectrometer dedicated to the analysis of CO₂ and Hydrogen.
• A manual drilling stage/computerized X-Y-Z micropositioning stage that allows for both bulk and fine sampling.
• A MicroMill computerized drill stage that allows for discrete sampling (i.e. daily to weekly growth banding in bivalves).
• Numerous extraction lines for the off-line preparation of gases for stable isotope determination.
