Multiresidue procedures for the determination of pesticides in food using capillary gas chromatographic, flame photometric, and mass spectrometric techniques

Organophosphorus pesticides are important for protecting many crops from insects. Multiresidue procedures for 10 organophosphorus pesticides were studied to establish analytical methods using capillary gas chromatography with flame photometric (FPD) and mass spectrometric detector (GC-MS). Quantitative gas chromatography with a FPD was examined to determine suitable chromatographic conditions for various GC columns. Gas chromatography with GC-MS was studied to choose proper fragment ions for determination and identification
