Application method of retention index in gas chromatography-tandem mass spectrometry analysis of tobacco flavor components

The invention relates to an application method of retention index in gas chromatography-tandem mass spectrometry analysis of tobacco flavor components. According to the method, the retention index isused for rapidly determining a collection time window in a gas chromatography-tandem mass spectrometry dynamic multi-reaction monitoring mode (dMRM) analysis method, and the method belongs to the technical field of tobacco component detection and is characterized in that a retention index database of a target compound is firstly established, and the retention time of the target compound can be predicted according to the actually measured retention time of n-alkane series on the basis of acquiring the database so that the time window of each target compound in the dMRM method is accurately andquickly created. The method has the advantages of rapidness, convenience and accuracy, and the workload of retention time correction is greatly reduced. 本发明涉及一种保留指数在气相色谱－串联质谱分析烟草香味成分中的应用方法，是利用保留指数快速确定气相色谱串联质谱动态多反应监测模式(dMRM)分析方
