- W2385038067 abstract "A rapid analytical method was developed for the determination of 14 heterocyclic aromatic amines(HAAs) in meat products by liquid chromatography-ion trap-time of flight tandem mass spectrometry(LCMS-IT-TOF).The samples were extracted with acetonitrile.The extract was cleaned up with Phenomenex strata-X-C,eluted with methanol-ammonia(9 ∶ 1),then evaporated with a stream of nitrogen to near dryness and redissoved with acetonitrile-water(1 ∶ 9).The separation of HAAs was performed on a Phenomenex Kinetex 2.6μ C18 100A(2.1 mm i.d.×100 mm,2.6 μm),using 30 mmol/L ammonium formate-acetonitrile as mobile phase by gradient elution.The analytes were detected under positive-ion electrospray ionization mode.Results showed that the linear ranges of 14 HAAs were 5-250 μg/L with limits of detection(S/N=3) of 0.59-3.27 μg/kg.The mean recoveries of all the compounds at three spiked levels of 10,50,250 μg/kg were in the range of 69%-107%,67%-106% and 76%-113%,respectively,with the corresponding RSDs(n=6) of 1.5%-15.6%,1.3%-11.8% and 1.8%-9.7%,respectively.The established method showed a wide liner range and a high sensitivity,and could meet the requirements for the simultanous analysis of the HAAs in meat products." @default.
