Abstract
Gas chromatography-mass spectrometry (GC-MS) is currently the most technical approach for the analysis of human body odor, which can be used to determine the composition of human body odor and compare the differences between different individual odors. This paper focuses on the application progress of GC-MS in human body odor analysis. First, the extraction and sample pretreatment of human body odor are briefly introduced. The applications of the human body odor analysis by GC-MS in collection and storage, the composition analysis and study of difference, and individual identification and health characterization are summarized. Finally, the application trends of GC-MS in human body odor analysis are discussed.
