Serviceship 1
CO2 extraction apparatus

We provide stable isotope ratio analytical services to researchers, government and commercial clients

SIGL provides 13C, 15N, 32S analyses on solid materials such as minerals, soils, sediments, animal and plant tissues via elemental analyser coupled to an isotope ratio mass spectromer (IRMS).

Carbonates (13C, 18O) and waters (2H, 18O) are analysed via dual inlet IRMS which is still industry gold standard.

Gas samples (13C, 2H) are analysed using a GC-c-IRMS while 13C in water is determined via Gas Bench.

Natural and enriched Waters and biological samples

Oxygen and hydrogen isotopes by equilibration using the Dual Inlet MS with multiprep bench

Carbonates and Forams

Carbon and oxygen isotopes both on-line with DI-multiprep and off-line vacuum systems thus allowing analysis of all species of carbonates (siderite, dolomite, calcite)

Sulfides, Sulfates and Hydrocarbons

δ34S and δ33S (MIF) analysis using the EA-CF-IRMS

Mineral separates, Quartz chips (fluid inclusions)

Hydrogen isotopes on mineral and clay separates using either the zero blank autosampler coupled with a TC-EA-IRMS or our off-line vacuum extraction system with RF generator.
