The gas geochemistry lab at IFPEN combines the instrumentation and expertise to analyse and interpret gas geochemistry data including:

• Major gas composition including CO₂, N₂, O₂, He, methane, ethane, propane, butane, H₂, H₂S

• Stable isotopic composition of carbon in CO₂, methane, ethane, propane, butane

• Stable isotopic composition of H in H₂, methane, ethane, propane, butane

• Noble gas concentration of traces of He, Ne, Ar, Kr, Xe

• Isotopic composition of He (³He/⁴He ratio) and Ar (⁴⁰Ar/³⁶Ar ratio)

Gas and water samples can be treated on demand, depending on sampling techniques and sample conditioning.

Procedures for sampling and conditioning should be advised.

 Instruments comprise:

• Triple detector (FID, 2 TCD), triple column, two carrier gas GC – gas sample and reference conditioning bench allowing thermostated, pressure regulated injection into the GC. Optimal absolute partial pressure calibration achieved for CO₂, N₂, O₂, He, methane, ethane, propane, butane, H₂, H₂S across the 0,001-100 vol.% range.

• Finnigan MAT253 IRMS coupled with Trace Gas GC and combustion/reduction interface. TriPlus automated sampler for various types of vials.

• GV 5400 sector mass spectrometer for Helium and Neon isotopes. Pfeiffer Vaccum Hi-Quad QMS700 (0-340 mass range) for noble gas elemental and Ar isotopic analyses. In house design UHV sample preparation line.
