This application note describes a method for simultaneous determination of 85 water quality regulated pesticides using Agilent GC/MS, including 76 organophosphorus pesticides, including 9 oxidation products and 5 oxidation products of fenitrothion. At a standard solution of 5 ppb, all pesticides can be detected, and the RSD (n=6) of the internal standard is 2.1-16.8%.
This document reports the results of a simultaneous analysis of 85 water quality regulated pesticides, including organophosphate oxon bodies and oxidation products of fenitrothion. The analysis was performed using an Agilent 7890 GC/5975C TAD MSD with 7693 ALS system. This manual is written in Japanese.
