摘要: 高精度准确测定类脂化合物单体同位素比值对重建古气候古环境具有重要意义.论述了古气候、古环境研究中适合单体同位素分析的类脂化合物提取、分离富集方法,介绍了单体化合物碳、氢同位素的仪器分析方法.

Abstract: The technique of gas chromatography-isotope ratio mass spectrometry (GC-IRMS) has obtained significant development since 1970s. The development make it possible to measure the compoundspecific isotope ratio of lipid biomarkers in organic matters. This paper presents the development in sample preparation (extration and separation), improvement of the instruments and analytical methods of GC-IRMS, and its applications in the research on paleoclimate and paleoenvironment reconstruction.
