Gas chromatography triple quadrupole tandem mass spectrometry(GC-MS/MS)is widely used in environmental monitoring and scientific research.It is also one of the important technologies for the analysis and detection of trace organic pollutants in the environment.In this paper,the experiment"Analysis of 16 kinds of polycyclic aromatic hydrocarbons by gas chromatography triple quadrupole tan-dem mass spectrometry"was designed for the experimental teaching of instrument analysis for environ-mental and related majors.In the experiment,the parameters of gas chromatography and mass spectrom-etry were optimized,and the effects of parameter changes on compound response,chromatographic peak separation and precision were discussed.The comparative method,multimedia and other teaching meth-ods are applied in the teaching.The teaching content was modularized and integrated to ensure the oper-ability of teaching practice and good teaching results.The knowledge units are comprehensive,which is conducive to improving students'analytical and practical ability and scientific research attainment.
