Simultaneous determination of trihalomethane and carbon tetrachloride in water
Simultaneous determination of trihalomethane and carbon tetrachloride in water Details:

Name: capillary column
Stationary Phase: 5% Phenyl-95% Methylpolysiloxane
Specifications: 30m*0.32mm*0.25um
Model: HH-5
Application: "GBT 5750.8-2006 Standard Test Method for Drinking Water-Organic Matter Index"

Trihalomethane and carbon tetrachloride are common disinfection by-products in water. When the concentration of trihalomethane and carbon tetrachloride in water is too high, it will cause harm to the human body. , carried out the detection of trihalomethanes and carbon tetrachloride, in order to improve the detection efficiency.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses headspace automatic sampling gas chromatography to determine chloroform and carbon tetrachloride in drinking water. By optimizing the three conditions of chromatographic conditions, equilibrium temperature and equilibrium time, the chromatographic conditions are determined. The ratio was 10:1, the carrier gas flow rate was 1.5 mL·min^(-1), the equilibrium temperature of headspace injection was 60 °C, and the equilibration time was 30 min. The method is simple, fast, simple, reproducible, and sensitive. Low and high precision, while improving the detection efficiency, suitable for batch sample detection of chloroform and carbon tetrachloride in drinking water.
