This study shows that the SPE-DEX® 4790 Automated Extractor system can process water samples containing suspended particulate matter, up to 1000 mg, for the analysis of PAH’s. As PAH’s are found in both the dissolved and particulate phase of the water sample, it is important to be able to handle “whole” water samples such that the particulate matter in the water sample is retained and extracted with the SPE disk. This filtration method ensures that the PAH’s found in the dissolved phase, and those adsorbed onto the particulate matter are properly extracted.

This work demonstrates the performance of automated solid phase extraction (SPE) for the extraction of PAHs from surface water sampled from a nearby pond containing some particulate. An automated system (Biotage® Horizon 4790) with Atlantic® DVB disks, following the requirements of method EN 16691, was used.

This application note describes the automated solid phase extraction (SPE) and GC/MS analysis of whole water samples according to EN16691 for PAHs. Method EN 16691 is a recently developed method that uses solid phase extraction to isolate organic compounds from 1 L of water using a divinylbenzene (DVB) solid phase extraction disk.

US EPA method 550.1 is a method used by regulatory agencies to determine PAH’s in drinking water by liquid-solid extraction (LSE) and high performance liquid chromatography (HPLC).1 The method outlines the steps needed to perform extractions of PAHs from drinking water sources and finished drinking water; as well as the quality control (QC) program requirements to ensure the method is operated under control. Use of Biotage automated sample preparation products allows users to achieve the precise and consistent data needed to comply with EPA method 550.1 QC specifications as stated in method, section 10.3.2., for Initial Demonstration of Capability (IDC); while at the same time, streamlining laboratory practices to increase lab productivity.
