Determination of Organophosphorus Pesticides in Water and Soil by OV-17 Capillary Column
OV-17 capillary column for the determination of organophosphorus pesticides in water and soil Details:

Name: capillary column
Fixative: 50% phenylmethylpolysiloxane
Specifications: 30m*0.53mm

Model: OV-17
Application: GB/T 14552-2003 Gas chromatographic method for the determination of organophosphorus pesticides in water and soil

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. proposed a method for the determination of 11 organophosphorus pesticides in water by solid-phase extraction separation-capillary column-gas chromatography. The water sample was separated and purified by solid phase extraction cartridge, and eluted with methanol-acetone (70+30) mixture. Separated by OV-17 chromatographic column (30m×0.53mm), detected by pulsed flame photometric detector. The mass concentrations of 11 organophosphorus pesticides were all within 5.00μg·L-1 and their peak areas were linearly related, and the lower limit of determination (10S/N) was between 0.03 and 0.05μg·L-1. The method was applied to the analysis of surface water samples and drinking water samples. The recoveries of standard additions were between 65.7% and 124%, and the relative standard deviations (n=6) of the measured values were between 1.8% and 9.9%.
