Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a method to determine the content of volatile components in polyvinyl alcohol resins. The method uses pervaporation headspace gas chromatography to analyze. The specific steps are: 0.1g~0.5g of the substance is sealed with a 20ml headspace bottle, put into the headspace sampler, heated at 115℃~125℃ for 85 minutes~95 minutes to completely evaporate the volatile components, using gas chromatography Analyze and record the spectra of volatile components, and then use the standard regression curve method to calculate the content of volatile components; the analysis conditions are: use HH-624 chromatographic column, use FID detector, column temperature 40℃, detector temperature 200℃; The temperature of the injector is 150℃. The method has good reproducibility of analysis data, accurate and reliable analysis data, simple operation, convenient operation, fast analysis speed, high sensitivity, and good separation effect of volatile components in the sample.
