This paper reviews the chromatographic analysis methods for gas samples in each link of the poly-vinyl chloride production process by the chlor-alkali-ethylene balance method of Haiwan Chemical.It intro-duces chromatographic separation technologies such as valve switching,backflushing and pre-separation used in chromatographic gas analysis and the applications of chromatographic detectors such as TCD,FID and FPD in gas analysis.The improvements and innovations of Haiwan Chemical in chromatographic gas analysis provide a reference for the application of gas chromatography technology in the analysis of gas samples in the chlor-alkali-PVC industry.
