Polycyclic aromatic hydrocarbons (PAH) in aqueous samples were collected in an online short enrichment column and separated by HPLC via a switching valve. The elutes were detected by UV and fluorescence in series. To obtain better selectivity and higher sensitivity, a manual fluorescence wavelength program was used for determing the trace PAH eluted. The optimum conditions for the enrichment of PAH were studied. The results of the determination of several PAH by online and off-line enrichment were also compared.
