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.

This Chemistry Data Sheet provides procedures for both the automated and manual fractionation of EPH in soil. The
automated procedure is described on page 2 and the manual procedure is outlined on page 3. Chromatograms
illustrate the ability of ISOLUTE EPH to provide efficient fractionation of hexane or pentane soil extracts into
aliphatic and aromatic fractions (see Appendix).
