- W2344888902 abstract "Purpose: Analyze the results of measuring the content of hazardous substances in food with the high performance liquid chromatography (HPLC)-mass spectrometry (MS) combination method. Method: (1) Establish the HPLC-MS to achieve the one-step extraction of the ethoxyquin antioxidant residue in honey peach and apple by extracting the analyte residue in alkaline sample solution with the help of N-hexane; then analyze it with the C18 chromatographic column and add a certain amount of ammonium acetate into the mobile phase to optimize the peak shape of chromatogram. (2) Establish the HPLC-MS to detect urotropin in food. Results: (1) It is found that the lower limit of detection with the HPLC-MS combination method is 5μg/kg, and the linearity range is between 20-200μg/L; all the recovery rates of different adding levels are between 8.65%-91.9%, and the RSD (relative standard deviation) is between 4.6%-5.4%. (2) For the HPLC-MS combination method, the 0.01mol/L ammonium acetate-acetonitrile is the mobile phase, which provides high accuracy and sensitivity, fits the treatment of a lot of samples, and is used for detecting urotropin to protect the health of consumers. Conclusion: The HPLC-MS combination method is highly feasible in measuring the content of hazardous substances in food." @default.
