Application of gas chromatography-ion mobility spectrometry in the analysis of food volatile components

Abstract Gas chromatography-ion mobility spectrometry (GC-IMS) is an emerging analytical technique that has the advantages of fast response, high sensitivity, simple operation, and low cost. The combination speed resolution GC with sensitivity IMS makes GC-IMS play important role in detection food volatile substances. This paper focuses on basic principles future development trend, comparative analysis functions, similarities differences GC-IMS, GC-MS electronic nose common compounds. A comprehensive introduction to main application components: fingerprint identification sample characteristic On basis perfecting spectral library, will have broad prospects authentication, origin identification, process optimization product classification, especially trace flavor
