Cryogenic Focusing with Liquid Nitrogen

Gas Chromatography – Isotope Ratio Mass Spectrometry (GC-IRMS)

Typically run on half of all mudgas Isotubes collected; selections are usually made after mudgas compositions are reported, as these can aid in isotope selections.

Measures the following:

Methane

Ethane (C2)

Propane (C3)

Butane (iso)

Butane (normal)

Pentane (iso)

Pentane (normal)

Deuterium

CO2

Gas Composition via Gas Chromatography

measures up to C6+

required prerequisite to Isotope analysis
