Current Capabilities of SIGF

• High-precision analyses and microanalyses of C- and O-isotopes in carbonates (Kiel IV, GasBench II)
• O and H isotopic analyses of water via equilibration and pyrolysis (GasBench II, TC/EA)
• Carbon isotopes in dissolved inorganic carbon (GasBench II)
• C and N isotopic analyses of bulk organic matter and oils (EA)
• N and O analysis of nitrates in water (GasBench II)
• Elemental results for C, N, O, and H (EA, TC/EA)

Oxygen Diatom

Future Capabilities of SIGF

• C and H isotopic analyses of specific organic compounds (e.g. gaseous hydrocarbons, lipids, lignitic compounds, etc.) (GC/C-IRMS)
• O analysis of organic based samples such as cellulose (TC/EA)
• O isotopic analyses of phosphates and sulfates via pyrolysis (TC/EA)
• H analysis of keratin based samples such as feathers and hair via pyrolysis (TC/EA)
• Inorganic S analysis (EA)
• Analysis of water samples using a laser based cavity ringdown system

Hydrogen Fuel

Using the Finnigan Gasbench II in combination with the PostCon cryotrapping options or the PreCon:

• ¹³C/¹²C of CO₂ in air (sub-ambient concentrations)
• ¹⁵N/¹⁴N and ¹⁸O/¹⁶O of N₂O in air (300 ppb)
• ¹³C/¹²C of CH₄ in air (1.7 ppm)
• ¹⁵N/¹⁴N and ¹⁸O/¹⁶O of N₂O
• ¹⁵N/¹⁴N and ¹⁸O/¹⁶O of nitrate using the Sigman technique
• ¹⁵N/¹⁴N of N₂ from micro-preparation systems

Flexible design allows use with lasers and Elemental Analyzers:
