Summary |
A mixture of 20 organophosphorus pesticide standards including azinphos methyl, boistar. chlorpvrifos, coumaphos, demeton. diazinon. dichion-os. disulfoton, ethoprop, fensuifothion, fenthion, merphos, methyl parathion. mevinphos, naled, phorate, ronnel, stirophos, tokuthion and trichloronate was analyzed by (IC MS method. The capillary column with 30 m in lengths and Summary 0.25 mm in diameter in (IC oven temperature was initiated at 50c3 for 1 mist increased to 300c3 by lOcJ mm and then maintained at 300c3 for 1 mm. The temperature of injector was 250c3. The flow rates of carrier gas (He) was maintained at 1 mL mm. A good separation and TIC of the standard pesticides was obtained under the mass spectrometry, scanning any mass ranged between rn z 50 mr 650.
