BIG NEWS! The Stable Isotope Laboratory (SIL) is now part of the new College of Earth, Ocean and Atmospheric Science (COEAS) formed by the merger of the College of Oceanic and Atmospheric Sciences and the Department of Geosciences.
The laboratory was founded in 1986 by director Dr. Alan Mix with a single Finnegan/MAT251 mass spectrometer. Today the laboratory, which is a member of the OSU Mass Spectrometry Consortium, operates four gas-source isotope ratio mass spectrometers (i.e., Finnigan/MAT252, ThermoFisher DeltaV-Plus, and two Thermo DeltaPlus-XL instruments) connected to a variety of peripherals (i.e., two Kiel-III carbonate prep. devices, a GasBench, a Water Equilibration system, two TCEA, two GC's, an EA, and one Precon). We analyze natural abundances of C, N, O and H isotopes in a variety of environmental, geological and biological sample types.
For information about analyzing samples please contact Dr. J. McKay (541-737-4054).
