Article Title: Simultaneous Determination of 24 Polycyclic Aromatic Hydrocarbons in Oils by Gas Chromatography-Mass Spectrometry Using an Improved Clean-up Procedure.
Publication date: 2019
Journal: Food Analytical Methods

Abstract: An improved gas chromatography-mass spectrometry (GC-MS) method was developed for the simultaneous determination of 24 polycyclic aromatic hydrocarbons (PAHs) in edible oils. A novel purification procedure based on the coupling double cartridges (molecular imprinting polymer (MIP) cartridge and PAHs special cartridge) was applied. Under the optimized conditions, the method presented excellent linearity (r ≥ 0.9990) in the range of 1.0-250 μg L-1, the detection limits were 0.1-1 μg kg-1, and high recoveries (86.0-116%) and good reproducibility (relative standard deviations (RSDs) ≤ 10.8) were also obtained using the two solid-phased extraction cartridges in combination. This method is sensitivity, accuracy, which can be used to detect 24 PAHs in edible oil samples
Template and target information: polycyclic aromatic hydrocarbons, PAHs
