Determination of 9 Organophosphorus Pesticides in Water by Capillary Column Gas Chromatography
Capillary Column Gas Chromatography Determination of Nine Organophosphorus Pesticides in Water Details:

Name: capillary column
Fixative: 5% phenylmethylpolysiloxane
Specifications: 30m*0.32mm

Model: HH-5
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. has established a method for the simultaneous determination of 9 organophosphorus pesticides including dichlorvos, dimethoate, malathion, methyl parathion, parathion, and chlorpyrifos in environmental water. The method adopts liquid -Determination by liquid extraction and HH-5 capillary column gas chromatography with flame photometric detector (FPD). Results The resolution of the aforementioned six organophosphorus pesticides was greater than 1.5, and the linear range was 2.0-16.0 μg/ml. The coefficient was greater than or equal to 0.999 2, the detection limit was 0.009 2-0.076 ng, the RSD was 1.5%-7.1%, the average recovery was 93.0%-98.7%, and the six organophosphorus were completely separated within 21 min. Compared with GB 13192-1991 "Determination of Organophosphorus Pesticides in Water Quality", its detection limit, precision and accuracy showed obvious advantages, which can meet the requirements of "Drinking Water Hygiene Standard" and the needs of daily analysis.
