This standard is the first industry standard for entry-exit inspection and quarantine.9 kinds of organophosphorus pesticides in import and export animal source foodsResidue detection method gas chromatography1 ScopeThis standard specifies the preparation and gas chromatography detection of 9 organophosphorus pesticide residues in import and export ham and pickled dried fish (鲞). method. This standard applies to dichlorvos, methamidophos, acephate, methyl parathion, malathion, parathion, and ham in ham and marinated dried fish (鲞). Detection of quetiapine, chlorpyrifos, and triazophos pesticide residues.2 sample preparationTake a representative sample of about 500g from all the samples of ham or marinated dried fish, pulverize with a pulverizer, mix evenly, and divide into two The parts were separately filled into a clean container as a sample. Seal and mark. Samples should be protected from contamination or changes in residue levels during sampling and sample preparation operations. Place the sample at -18 ° C Save in the refrigerator.3 test methods3.1 Method summary The sample was extracted by shaking with acetonitrile, purified by a gel column, and determined by a gas chromatograph equipped with a flame photometric detector, and quantified by an external standard method. 3.2 Reagents and materials All reagents were of analytical grade and water was distilled water unless otherwise stated. 3.2.1 Ethyl acetate. chromatographically pure. 3.2.2 Acetonitrile. chromatographically pure. 3.2.3 Cyclohexane. chromatographically pure. 3.2.4 GPC eluent. ethyl acetate + cyclohexane (1+1, 犞/犞). 3.2.5 dichlorvos standard. purity greater than 99%; methamidophos standard. purity greater than 99%; acephate standard. purity greater than 99%; methyl parathion standard. purity greater than 99%; malathion standard. purity greater than 99%; parathion standard. purity greater than 99%; quetiapine standard. purity greater than 99%; killing phosphorus standard. purity greater than 99%; triazophos standard. purity greater than 99%. 3.2.6 dichlorvos, methamidophos, acephate, methyl parathion, malathion, parathion, quetiapine, chlorpyrifos, triazophos standard reserve Solution. Weigh 0.0100 g of the standard (3.2.5), respectively, and dissolve to a volume of 100 mL with acetone, and the solution concentration is 100 μg/mL. Pro Dilute to the appropriate concentration with acetone as needed before use as a mixed standard working solution. 3.3 Instruments and equipment 3.3.1 Gas Chromatograph. equipped with a flame photometric detector (phosphor filter 525 nm). 3.3.2 Rotate the evaporator. 3.3.3 Gel purification finished column (GPC). 25mm (inside diameter) × 400mm; packing.
