| Abstract: | A method was developed for determining residual metaldehyde in vegetable by liquid chromatography with tandem mass spectrometry.The samples were extracted with acetonitrile.Then the extract was dried under nitrogen after salting-out.Further cleanup was performed on a florisil cartridge.The elution was dried under nitrogen and residues were dissolved in acetonitrile/20 mmol/L ammonium acetate solution(70/30,V/V).The samples were analyzed by LC-MS/MS on a XBridgeTM C18 column with a mixture of acetonitrile an... |
