Detailed information on the role of trace amounts of 1,2-dichloroethane in ethylene epoxidation using packed columns: The role of trace amounts of 1,2-dichloroethane in ethylene epoxidation was determined using a packed column test spectrogram:Determination of Trichloromethane Tetrachloride in Drinking Water by Gas Chromatography

Detailed information on the determination of chloroform and carbon tetrachloride in drinking water by gas chromatography:



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a gas chromatography method for the determination of chloroform and carbon tetrachloride in drinking water. Methods: Manual injection, DC550 column and electron capture detector were used for determination, and external standard method was used for quantification. The working parameters and analytical method of the instrument were optimized. Results: The mass concentrations of chloroform and carbon tetrachloride were between 0 and 9.11 μ G/L and 0-4.57 μ Within the range of g/L, there is a linear relationship with the peak area of the chromatogram, with correlation coefficients of 0.9998 and 0.9998, and a detection limit of 0.2 μ G/L and 0.1 μ G/L, with a recovery rate of 98.4% to 102% for chloroform and 96.8% to 101% for carbon tetrachloride. Conclusion: The method has the characteristics of simple operation, fast analysis speed, high accuracy, good precision, and low detection limit, and is suitable for the determination of chloroform and carbon tetrachloride in drinking water
