Determination of Polycyclic Aromatic Hydrocarbons (PAHs) in Tap Water Using On-Line Solid-Phase Extraction Followed by HPLC with UV and Fluorescence Detections

Numerous polycyclic aromatic hydrocarbons (PAHs) are carcinogenic, making their presence in foods and the environment a health concern. This application note details an online SPE method followed by HPLC with fluorescence and UV detections on the UltiMate 3000 ×2 Dual HPLC system for determining the 16 PAHs specified in the US EPA Priority Pollutants List at the concentrations required by world regulatory agencies.
