Abstract The GLC method described is specific for measuring 4 components of Phosphamidon Insecticide—deschlorophosphamidon, α-phosphamidon, β-phosphamidon, and γ-chlorophosphamidon. The sample is extracted with acetone, an internal standard (dicyclohexyl phthalate) is added, and the solution is diluted to volume and injected into a gas chromatograph equipped with a flame ionization detector. Although the GLC peak areas for phosphamidon are not linear over a wide range of concentration, good results are obtained when sample and standard concentrations are matched to within 10%. A 1.21% coefficient of variation was found for 19 repetitive injections.
