| Abstract: | An ultra performance liquid chromatography-tandem mass spectrometric(UPLC-MS/MS) method was developed for the determination of sucralose in foodstuffs.The sample was extracted with water.Different purificatory methods like HLB cartridge purification or precipitators removing fat and protein were chosen according to different sample matrixs.The extract was separated with reversed-phase UPLC column using a binary eluent under isocratic conditions,and determined by tandem mass spectrometry under negative elect... |
