1
Isotope Ratio Mass Spectrometers (IRMS)
IECS currently houses three continuous flow Thermo Finnigan IRMS (Deltaplus, a Deltaplus XL and a Delta V) allowing the qualification of C, H, N, O, and S stable isotope ratios.
Peripherals include two Costech ECS 4010 Elemental Analysers, a Thermo Quest TC/EA, two Thermo Scientific Gas Benches II and a Thermo Scientific GC Combustion II enabling analyses of solid, liquid and gas samples.
2
Cavity Ring-Down Spectrometers (CRDS)
IECS currently houses two CRDS systems
-
· Picarro G1111-i coupled to an OI Aurora 1030 W Total Carbon Analyzer for concentrations and stable isotope ratio measurements of CO2, DIC and DOC
-
Picarro L2120-i coupled to a PAL HTC-xt auto sampler for analyses of hydrogen and oxygen stable isotope ratios in water
