ISOLUTE EPH SPE columns and associated methodologies have been optimised to efficiently fractionate EPHs into aliphatic and polycyclic aromatic (PAH) fractions. The principle is similar to the approach taken by the Massachusetts Department of Environmental Protection (MADEP) and TPH criteria working group (TPHCWG) methods. However, compared to these methods, the ISOLUTE EPH fractionation column has been significantly reduced in size and the sorbent has been optimised in order to reduce solvent volumes and provide an automation compatible fractionation column. Automation of the fractionation process has been achieved without carryover of PAHs into the aliphatic fraction.

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.
