Polynuclear aromatic hydrocarbons (PAHs) consist of a large group of organic compounds with two or more fused aromatic rings. EPA method 8310 is a performance-based hazardous waste test method (SW-846) regulated under the Resource Conservation and Recovery Act (RCRA), which allows analysts to modify sampling and analytical approaches flexibly to
meet the measurement requirements and is capable of determining 16 PAHs.

This application note outlines a solid-phase extraction (SPE) procedure using C18 SPE universal cartridges to extract 16 PAHs in water. The target PAHs are retained on the C18 sorbent, and are later eluted with acetone and dichloromethane (DCM). Sodium sulfate drying cartridges are used to remove any residual water in the SPE eluates. The dried eluates are concentrated, exchanged to acetonitrile, and analysed by HPLC with
ultraviolet (UV) or fluorescence detectors (FLD).
