Abstract

Five food samples have been analysed for a number of polycyclic aromatic hydrocarbons (PAHs) by capillary gas chromatography with flame ionization detection (GC-FID) and high-performance liquid chromatography (HPLC) with fluorescence detection. The methods give similar results and there is no significant difference in their repeatability. The capillary GC method is favoured where it is desirable to analyse for a large number of PAHs, whereas the HPLC method is preferred for the individual analysis of a smaller number of PAH isomers.

摘要

已通过带有火焰离子化检测的毛细管气相色谱法(GC-FID)和带有荧光检测的高效液相色谱法(HPLC)对五个食品样本中的多种多环芳烃(PAHs)进行了分析。这两种方法得出的结果相似,其重复性也没有显著差异。当需要分析大量多环芳烃时,首选毛细管气相色谱法,而对于较少数量的多环芳烃异构体的单独分析,更倾向于使用高效液相色谱法。
