| titleOfInvention | Liquid Chromatography/Mass Spectrometry 7 kinds of benzene polyacid of detection and derivative specific transfer metering method thereof |
| abstract | The present invention provides 7 kinds of benzene polyacid of five kinds of food simulants of a kind of mensuration simultaneously and the high performance liquid chromatography tandem mass spectrum method for combined use of the specific gross migration of derivative thereof.Food simulants soaks testing sample, is cooled to room temperature and mixes, aqueous-based food analogies sample introduction after the filtration of hydrophily polytetrafluoro acetic acid syringe filters；Vegetable oil with after 0.1% ammonium formate extraction with aqueous solution, lower clear liquid hydrophily polytetrafluoro acetic acid syringe filters filter after sample introduction.Separate with Synergi Polar RP post isocratic elution；Mass spectrum has electric spray ion source, run under anion multiple-reaction monitoring pattern, the method chromatographic isolation and linear relationship are preferable, the rate of recovery and the degree of accuracy are high, the limitation meeting the specific gross migration of 7 kinds of benzene polyacid and derivative thereof in European Union NO 10/2011 regulation requires, and has been applied to the detection of actual sample. |
