CPSIL currently houses three Thermo Electron gas isotope-ratio mass spectrometers and several preparation devices.  A fourth mass spec (Delta V) and second Gas Bench (for carbonates) is scheduled for installation in March 2006.

1. The DELTA ^plus Advantage is configured through the CONFLO III for automated continuous-flow analysis of C, N, or S isotopes in solid inorganic/organic samples using our Carlo Erba NC2100 Elemental Analyzer (EA) or our Costech ECS4010 Elemental Analyzer.

2. The DELTA ^plus XL is configured through the CONFLO II for automated continuous-flow analysis of O and H isotopes in solid inorganic/organic samples via high-temperature pyrolysis (TC/EA).  The XL is also interfaced to our Gas Bench II for automated analyses of O and H isotopes in water.  The XL is also interfaced with our O.I. Analytical TOC analyzer for measurement of C isotopes in water (DIC and DOC).  The XL is also interfaced with our two elemental analyzers for C, N, or S isotopes in solid inorganic/organic samples.

3. The DELTA ^plus is configured for classic dual-inlet analyses of H, C, N, O, and S isotopes of pure gases (H₂, CO₂, N₂, SO₂, O₂) using a multi-port tube cracker for batch samples.  The Plus is also configured for continuous-flow analysis of N, O, and C isotopes in trace gases (N₂O, CH₄, and CO₂) at atmospheric concentrations using a Thermo Finnigan Precon.  The Plus is also interfaced with our new Trace GC-C system for C isotopes in compound-specific analyses.

In summary, we can determine C, N, S, O, and H isotope compositions of gases (either purified or in mixtures at atmospheric concentrations), organics (solid and liquid, of plant and animal origin), inorganics, and waters.
