Objective: To set up the analysis methods of chlorohydrocarbon in water.Methods: With optimization of chromatographic conditions and headspace conditions,the automatic headspace capillary gas chromatography was adopted to determine chlorohydrocarbon in water.Results: The seven kinds of components were completed determination in 10 minutes with good separation efficiency. There was good linearity with correlation coefficient of 0.998. The established method was used for the determination of synthetic water s...
