A method has been developed to detect diphenylamine, o-phenylphenol, a
nd propargite on apples. Gas chromatography mass spectrometry was used
to identify and quantify three compounds in the selective ion monitor
ing mode. The limits of detection are 10, 9, and 15 ppb for diphenylam
ine, o-phenylphenol, and propargite, respectively. The method provides
excellent recovery and linearity data with low coefficients of variat
ion for the three pesticide residues.
