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

This application note describes the extraction of polyaromatic hydrocarbons (PAHs) from natural waters with a high concentration
of humic acids. Layered SPE columns are used to eliminate humic acids from the final extract.

This technical note describes the use of layered SPE columns in applications where multiple suites of analytes with a broad polarity range are to be extracted simultaneously from a single water sample, such as organochlorine, triazine and organophosphate pesticides, or endocrine disrupters.

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.
