Compound-specific isotope analysis has been developed recently using gas chromatography/combustion/mass spectrometry (GC/C/IRMS). This paper summarizes principles and progress of GC/C/IRMS, and reviews recent some important works using this new method. GC/C/IRMS is a novel tool for (i) biomarker analysis in sediments and living matter, (ii) paleoenvironment analysis including reconstruction of ancient biogeochemical processes, (iii) geochemical cycle study of organic compounds in a terrestrial-marine system, (iv) evaluation of maturity and diagenesis of organic matter including petroleum formation, (v) ecological analysis, (vi) evaluation of anthropologenic pollution in environment, (vii) detection of extraterrestrial organic compounds and the formation mechanism study, (viii) tracer studies in environment.
