Rapid determination of polycyclic aromatic hydrocarbons (PAHs) in tea using two-dimensional gas chromatography coupled with time of flight mass spectrometry
Original language description
A simple, fast, and cost effective sample preparation procedure has been developed and validated for the determination of 15+1 European Union Polycyclic Aromatic Hydrocarbons (15+1 EU PAHs) in dried tea leave samples. Based on a critical assessment of several sample extraction / clean-up approaches, the method based on the ethyl acetate extraction followed by the use of PAHs dedicated cartridges with molecularly imprinted polymers (MIPs) has been found as an optimal alternative in terms of time demandsand obtained good extract purity. For the final identification / quantification of target PAHs, two dimensional gas chromatography coupled to a time-of-flight mass spectrometry (GCxGC-TOFMS) was used. The performance characteristics of the overall analytical method for individual PAHs determined at three spiking levels (0.5, 2.5 and 5 ?g.kg-1) were in following ranges: limits of quantitation (LOQs) 0.05-0.2 ?g.kg-1, repeatabilities 2-9%, and recoveries 73-103%.
