Stable isotope measurements
Isolab owns four state-of-the-art Isotope Ratio Mass Spectrometers each coupled to a modern GC (GC-IRMS), which are used to analyse the isotope ratio of your geochemical samples. Some common asked analyses are:
- d13C isotopes of light hydrocarbons (C1-C5) in compressed gasses and mud gasses (headspace).
- dH isotopes of light hydrocarbons (C1-C5) and hydrogen in compressed gasses and mud gasses.
- d18O and d13C of CO2.
- d15N of nitrogen.
- d13C of whole oils or fractions (by Elemental Analyser-IRMS).
- d13C of solid carbon samples (by Elemental Analyser-IRMS).
Eight modern Gas Chromatographs (GC's) are used to analyze chemical compositions of oil and gas samples. The chemists of Isolab are always alert for unexpected compounds in the samples and will contact the customer when action is needed.
Some of the possible analyses are:
- Composition (C1-C5, C6+, H2, N2, CO2, O2) of compressed gasses.
- Composition (relative amount of C1-C5 and absolute concentration of C1) of mud gasses or headspace samples.
- Composition of light compounds (C6-C8) in gas and oil samples.
- Fingerprinting of whole oil samples (C7-C25) by GCxGC.
- Analysis of a certain group of components in an oil by GCxGC (for instance mono-aromatics or di-aromatics).
