Popis:	The analysis of polynuclear aromatic hydrocarbons (PAHs) has been widely practiced using liquid-liquid extraction as a method of sample clean-up and sample enrichment. For the analysis of PAHs by HPLC, alternative sample preparation methods using solid-phase extraction or precolumn concentration have been reported. These methods normally required a switching valve and/or pump in addition to the HPLC system. This study reports a precolumn concentration method using no additional valve or pump to the HPLC system. The method is evaluated for recoveries, reproducibilities, linearity and minimum detection limits.
