Analysis of Low Level Pyrethroid Pesticides in Water

In this study, a simple method for isolating pyrethroids from water at low ng/mL levels was performed using solid-phase extraction (SPE) followed by GC/MS utilizing a programmable temperature vaporizer (PTV) operated in simulated on-column injection mode. The separation of the pyrethroid (bifentrin, permethrin, cyfluthrin, cypermethrin and flumethrin) extracts was carried out using a Thermo Scientific™ TraceGOLD™ TG-5SilMS column and GuardGOLD™ pre-column.
