摘要

The resolution of organic compounds from sediments is increased by ¹³C/¹²C isotopic gas chromatography-combustion-mass spectrometry relative to gas chromatography with flame ionization detection. Impurities which elute close together with n-alkanes, phytane and a C₃₂ hopanoid acid methyl ester are resolved with a valley increase of up to 100%. This phenomenon is probably due to fractionation during gas chromatographic elution and enhanced detection monitoring of the isotopic composition of the carbon dioxide produced by the combustion of the eluting substances.
