High-performance liquid and gas chromatography of dialkylphosphates, dialkylthiophosphates and dialkyldithiophosphates as their pentafluorobenzyl derivatives.
High-performance liquid and gas chromatographic (GC) procedures for the separation and determination of dialkylphosphates, dialkylthiophosphates and dialkyldithiophosphates (alkyl = methyl or ethyl), the main hydrolytic metabolites of organophosphate pesticides, are described. The application of different procedures and their limits of detection are discussed. The GC proposed procedures were applied to the analysis of urine samples from humans exposed and not exposed to organophosphates.
