9 kinds of organophosphorus pesticides in import and export animal source foods
Residue detection method gas chromatography
1 Scope
This 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 preparation
Take 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.
