Instrumentation

Our lab consists of 4 Thermo isotope ratio mass spectrometers, with a collective 8 peripheral elemental analyzers, thermal conversion analyzers, gas-benches, and a gas chromatograph with combustion/pyrolysis module. These monolithic analyzers are sensitive and robust, allowing for a variety of applications. 

Elemental Analyzer Instrument
EA-IRMS

Elemental analyzers are used for organic elemental analysis of Nitrogen, Carbon, and Sulfur, using the Dumas Method.

TCEA-IRMS

Temperature conversion elemental analysers are used to analyze isotope ratios of hydrogen and oxygen in solids and liquids. 

Gas Bench Instrument
GB-IRMS

GasBench-IRMS is used to measure isotope ratios of carbonate, nitrate dissolved in water, air, and dissolved inorganic carbon.

A Picarro L2140-I Cavity Ring Down Spectrometer is used to measure the isotope ratios of hydrogen and oxygen in water.

Gas Chromatograph Instrument
GC-C-IRMS

Compound specific isotope analysis (CSIA) analyzes isotope ratios of carbon and hydrogen in specific compounds through the use of gas chromatograph separation coupled to either combustion or pyrolysis interfaces.
