Extractable Petroleum Hydrocarbons (EPH) Fractionation and Bottlenecks in the Laboratory

Anyone familiar with EPH methods such as those developed by the Massachusetts or New Jersey Department of Environmental Protection is familiar with the long and gruelling process of fractionation. For those unfamiliar, with EPH or Extractable Petroleum Hydrocarbons it is an extraction that essentially occurs in two distinct parts: the initial extraction & concentration and then the fractionation of that initial extract into the aromatic and aliphatic fractions followed by concentration again.  EPH is a method that replaces the TPH (Total Petroleum Hydrocarbons) or 8015 methods and allows for the calculation of specified carbon ranges giving you a more accurate assessment of potential health risks.
