快速GC分析EPA 和 EU 规范的PAHs多环芳烃

快速GC分析EPA 和 EU 规范的PAHs多环芳烃 Introduction After assessing 33 PAHs, the European Commission Scientifi c Committee on Food (SCF) in 2002 found that due to their toxicity, 15 of them were of major concern to human health and should therefore be monitored. The FAO/WHO Expert committee on Food Additives identifi ed benzo(c)fl uorine in 2005 as an additional compound that should be analyzed. These 15+1 EU priority PAHs differ from the 16 PAHs covered under the US EPA regulations. With the increase of the number of target PAH analytes and the fact that many PAHs and their isomers exhibit identical MS mass fragmentation, the chromatographic separation and selectivity of the stationary phase for the analysis of PAHs has become more important. This application note illustrates the successful use of a VF-17ms column from Varian, Inc. for the fast GC/MS analysis of most PAHs listed in the EU and EPA regulations (Figure 1).
