Gas Isotope Ratio Mass Spectrometers

Mass spectrometry for analyzing stable oxygen and carbon isotopes in carbonates, and isotopes in inorganic carbon dissolved in water.

Determination of the stable isotopic compositions of C, H, N, O, S on organic compounds (lipids) in solid and liquid (e.g., seawater) samples.

Mass spectrometry for measuring stable H, C, N isotopes on organic compounds in sediment samples and cell material.
