Determination of polycyclic aromatic hydrocarbons(PAHs) in vegetable oil by gas chromatography coupled with triple quadrupole mass spectrometry based on an isotope dilution
An efficient and selective analytical method for the determination and the quantification of 15 EU priority polycyclic aromatic hydrocarbons( PAHs) in vegetable oil has been developed. The samples were extracted by acetonitrile / acetone( V: V = 60: 40) followed by a purification with gel permeation chromatography( GPC). Identification and quantification were performed using GC-MS / MS with selected reaction monitoring( SRM) mode,with an isotope dilution approach. The novel combination of selective extracti...
