| Abstract: | In this paper,determination of chlorinated polyvinyl chloride （CPVC） products in total carbon volatilization of organic volatile matter by headspace-gas chromatography （HS-GC）. ,based on the equilibrium temperature and equilibrium time and sample particle size of exploratory testing, the optimum conditions of this method were determined. Using acetone as the external standard, the linear correlation coefficient of the standard curve obtained is 0.9998 , the relative standard deviation is 1.36, the recovery rate of up to 99.8%. |
