摘要:
According to the teaching characteristics of gas chromatography instrument, the teaching content is decomposer] into different modules such as sample pre-treatment, instrument structure, technical principle, qualitative analysis, quantitative analysis, core components of the production, maintenance and troubleshooting and so on. We use a variety of leaching methods such as program design, structure analysis, instrument operation, maintenance and trouble-shooting, and select a combination of different modules and different teaching methods according to different professional training objectives and different levels of demand to suit different professions and different levels in the project. Teaching makes students grasp the basic connotation of the gas chromatograph (instrument structure, technical principle, instrument parameters, qualitative analysis, quantitative area normalization method, chromatography software). According to the different needs of different levels the professional connotations can be extended to the sample pre-treatment, the preparation of standard solution, internal standard method, external standard method quantitative and instrument maintenance and troubleshooting module. The skills of the students have been trained through the standard process of teaching, and good teaching results are achieved. [ABSTRACT FROM AUTHOR]
