Packed column headspace method for benzene series in drinking water
Packed column headspace method for benzene series in drinking water Details:


Name: U-shaped or spiral-shaped glass column
Specification: 2m*2mm inner diameter or 3mm
Model: 10%OV-101/CHROM WHP 80-100 mesh
Application: GB/T 5750.8-2006 Standard Test Method for Drinking Water Organic Substance Index

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a headspace gas chromatography method for the determination of trace benzene series in drinking water. The separation of each component is good. The detection limits of benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene, and cumene are 0.002, 0.004, 0.005, 0.007, 0.007, 0.008, 0.005 mg/L, respectively, and the average addition of the sample The recovery rate is 97.0%-100.8%, and the relative standard deviation of the measurement results is not more than 5.1% (n=5). This method can meet the detection requirements of benzene series in water.
