Fractionation of EPH using a novel automation platform for column-based extraction

Characterization of hydrocarbon environments in soil and sediment can be an extremely cumbersome and time-consuming process. Separation of aliphatic and aromatic fractions is not always straightforward. The Massachusetts Department of Environmental Protection (MADEP) and TPH criteria working group (TPHCWG) methods rely on the use of large volumes of solvent to achieve this end. As part of our environmental goals, we are all looking to reduce solvent consumption wherever possible. This poster presents column-based methodologies allowing the efficient fractionation of EPHs into aliphatic and polycyclic aromatic hydrocarbons using drastically reduced solvent consumption.  Increased sample throughput was achieved by method transfer to a dedicated automated SPE platform performed.
