Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a headspace 15%DC-550/Chromosorb W AW packed column gas chromatography method for the determination of chloroform and carbon tetrachloride in drinking water, and at the same time investigated chloroform in drinking water from different sources The distribution of chloroform and carbon tetrachloride in water. The method adopts headspace automatic sampling technology. Determination of chloroform and carbon tetrachloride in water by specific 15%DC-550/Chromosorb W AW packed column gas chromatography. Results of standard curve The correlation coefficient was >0.999, the relative standard deviation was 1.5%~8.3%, the average recoveries of chloroform and carbon tetrachloride were 97.5%~103.3%; The output limit is 0.02μg/L; the linear range of carbon tetrachloride is 1.0~5.0μg/L, and the detection limit is 0.003μg/L. Conclusion The method is simple, rapid, has good precision and accuracy, and can be used for Determination of chloroform and carbon tetrachloride in water.
