[Multiresidue analysis of pesticides in agricultural products by GC/MS, GC-ECD and GC-FTD using acetonitrile extraction and clean-up with mini-columns].

An analytical method was developed for determination of organochlorine, pyrethroid and nitrogen-containing pesticide residues in agricultural products by GC/MS, GC-ECD and GC-FTD. Pesticides were extracted with acetonitrile, and the organic layer was cleaned up on C18 and ENVI-Carb/LC-NH2 cartridges. Pesticides were determined by GC/MS, GC-ECD and GC-FTD.
