Abstract

Abstract Diazinon and 5 of its known or suspected transformation products were chromatographed on thin layer sheets and thin layer silica gel plates, using a variety of solvents. Ten chromogenic sprays with sensitivity ranges from 0.05 to 1 μg were used to identify the migrated compounds on the thin layer chromatogram. Two-dimensional TLC separated all the compounds in a single procedure. Several crops fortified at levels of 0.5 to 2.0 ppm were successfully analyzed for these compounds.
