Determination of Epichlorohydrin in Drinking Water by Purge and Trap/GC/MS Details:

Name: capillary column
Stationary phase: 6% nitrile propylphenyl 94% dimethylpolysiloxane,
Specifications: 60m*0.32mm*1.8um
Model: OV-624
Application: Water Quality Determination of Epichlorohydrin Liquid-Liquid Extraction/Gas Chromatography-Mass Spectrometry

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method for the determination of epichlorohydrin in drinking water by purge and trap-gas chromatography-mass spectrometry. Methods The epichlorohydrin in water was enriched by a purge trap, and the desorption temperature was 250 ℃ and the gas inlet temperature was 160 ℃. It was determined by gas chromatography-mass spectrometry, and the characteristic ion 57 m/z was selected for quantification. Results When the concentration of epichlorohydrin in the water was 0μg/L~20.0μg/L, the linear correlation coefficient was r0.999, and according to 1.0μg/L, 6.0 The recoveries were 84.9%, 91.0%, and 104.3%, the precisions (RSD%) were 7.3%, 6.5%, and 4.1%, and the detection limit was 0.04 μg/L. Conclusion This method can easily, quickly and effectively separate and detect epichlorohydrin in water, and simultaneously analyze other 30 kinds of volatile organic compounds, which can meet the detection requirements of volatile organic compounds in drinking water.
