分析说明
This application illustrates the analysis of 29 different agricultural pesticides of different classifications and functionalities. The analysis was done by GC-MS using selected ion monitoring (SIM) to allow detection of all compounds at 100 μg/L. The
standard solution was made in toluene to increase it stability and enhance response of some of the pesticides. The extra peaks in the first portion of the run are due to interferences from the solvent.
