Stable Isotope Ratio Mass Spectrometry Facility

Lab Manager: Ethan Goddard

The Stable Isotope Ratio Mass Spectrometry Facility is capable of measuring the carbon, nitrogen, oxygen, and hydrogen stable isotope compositions in a variety of geologic and biologic materials including carbonates, waters, tissues, plants, bone/enamel/apatite and isolated organic compounds (alkanes, fatty acids, biomarkers).

Facility Instrumentation:

Thermo MAT253 IRMS w/ dual-inlet and continuous-flow inlets coupled to a Gas-Bench II prep device for headspace analysis of CO2 (DIC, carbonates, water-d18O)

Thermo Delta+XL IRMS w/ continuous-flow inlet coupled to Carlo-Erba 2500-II EA, Thermo TC/EA, Gas-Bench II headpace sampling device and Thermo GC-C/TC for compound-specific d15N, d13C, d18O, dD stable isotope analysis of GC amenable compounds (typically fatty-acids, amino-acids, alkanes/hydrocarbons)

Thermo Delta+XL IRMS w/ dual-inlet coupled to Kiel-III carbonate preparation system
