Isotopic signatures of oil compounds can give insights into the origin and quantitative source assessment of deep oils, as well as unravel both biogenic and thermogenic alterations and sources in crude oils. Also, the carbon and sulphur isotopic composition of crude oil can give insights into the source of crude oil spills.

Using the Thermo Scientific™ Delta V™ and 253 Plus™ Gas IRMS instrumentation one can determine not only the makeup of a complex hydrocarbon mixture, but also the stable isotope composition of each molecular component of the mixture. The Thermo Scientific™ Neptune Plus™ MC-ICPMS coupled with Gas Chromatography is best suited to obtain highly precise compound-specific analysis of sulphur isotopes in oil and its compounds..
