Pulsed pyrolysis (Py) in combination with atmospheric pressure ionization (API) and tandem mass spectrometry was investigated as a method for detecting 1,3,5‐triazine pesticide residues in agricultural matrices with minimal sample preparation. Analytes investigated were thermally stable and produced Py‐API mass spectra that contained essentially only the protonated molecule. Collision‐induced dissociation yielded daughter ions attributable to cleavage of the triazine ring. Limits of detection for analytes in crop samples ranged from 10 −1 to 10 2 mg residue per kilogram of substrate, depending on the nature of both analyte and substrate.
