Simultaneous detection of five kinds of poultry meat products organotin pesticides secondary mass spectrometry

Preparation of standard working solution derived; volume of acetonitrile to extract the organic tin, derivatized and purified - tandem mass spectrometry method for simultaneous detection of five kinds of poultry meat organotin pesticide residues, according to the desired protein in the sample is determined formic acid , five, organotin azocyclotin, cyhexatin, triphenyl tin hydroxide, triphenyl tin chloride and fenbutatin oxide, there are three derivative by gas chromatography - triple quadrupole mass spectrometry, to give standard curve; external standard method using three kinds of detecting pesticide residues organotin derivative: was analyzed by a standard curve, obtained with organotin concentration of pesticide residues in the sample. The present invention makes use of GC-MS / MS detection method having high sensitivity, it established the protein extract was added in an amount in accordance with, a fracture and two way mass three organic tin derivative was resolved, and mass spectra established specific conditions, it is a fast and efficient in animal foods organotin pesticides detection method.
