| titleOfInvention | A kind of method analyzing multiple incretion interferent in mensuration food |
| abstract | The invention belongs to field of food inspection, relate to the analysis determining method of incretion interferent in food, be specifically related to a kind of method analyzing multiple incretion interferent in mensuration milk powder and liquid milk.The present invention adopts water sample dissolution, after adding the ultrasonic extraction determinand of the organic solvent miscible with water, adds sodium salt, makes organic solvent and aqueous phase separation, realize liquid-liquid extraction; Get the machine solvent quantitatively had containing determinand, through the Solid phase extraction of C18 filler, after dansyl chloride is derivative, analyzes with Ultra Performance Liquid Chromatography series connection quadrupole rod time of-flight mass spectrometer simultaneously and measure 26 kind of 4 class incretion interferent in food.The inventive method can make up in prior art and can not realize the defect that chromatography column feed materials analyzes multiple incretion interferent in food simultaneously, the sensitivity of quadrupole rod time of-flight mass spectrometer can be improved simultaneously, realize the accurate analysis of incretion interferent quadrupole rod time of-flight mass spectrometer in food. |
