| Abstract: | A liquid chromatography-tandam mass spectrometric(LC-MS/MS) method was developed for determination of bitertanol residue in brown rice,corn,barley,wheat,buckwheat,rice,broomcorn and oat.The sample was extracted with acetonitrile,and cleaned up by NH2 solid phase extract column.The extract was determined by liquid chromatography-tandem mass spectrometry and quantified by external standard method.The quantitative limit was 0.025 mg/kg.The recoveries of bitertanol in cereals at three spiked concentration level... |
