BMF 61 - GC-IRMS - Gas Chromatography Isotope Ratio Mass Spectrometry

GC-IRMS offers an elegant, simple and increasingly popular method to determine the carbon isotopic composition (13C/12C) of individual hydrocarbons. The ratio of these isotopes in natural materials varies slightly as a result of isotopic fractionation due to physical, chemical and biological processes. Carbon isotope ratios can be used to establish the relationship between organic compounds and their source materials. It changes with the age of the material and is therefore used in geological determination.


Standards for individual n-alkanes with 11 to 40 carbons and verified δ13C values are available from Chiron!
