Determination of Polycyclic Aromatic Hydrocarbons(PAHs) in Vegetable Oil by Gas Chromatography Coupled with Triple Quadrupole Mass Spectrometry Using Isotope Dilution
An analytical method for the determination of 16 types of polycyclic aromatic hydrocarbons(PAHs) in vegetable oil has been developed.Samples that had been spiked with isotope standard solution were extracted using acetonitrile/acetone(60:40,V/V) and purified by gel permeation chromatography(GPC).Identification and quantification were performed using gas chromatography-triple quadrupole fandem mass spectrometry(GC-MS-MS) in the selected reaction monitoring(SRM) mode.The efficiency of GPC was compared with th...
