Compound-specific isotope analysis is applied to obtain information on isotope ratios (δ¹³C, δD) of defined organic matter.
Gas chromatography coupled to isotope ratio mass spectrometry is applied to determine compound-specific isotope ratios (δ¹³C, δD) of hydrocarbons in crude oils, gas samples and organic extracts from sediments, rocks, soils, water, plants and microorganisms to (1) investigate biogeochemical processes such as biodegradation of petroleum, (2) evaluate origin and fate of …
