An Automated Method for the Fractionation of Extractable Petroleum Hydrocarbons (EPH) from Water and Soil Extracts

Crude and refined petroleum products contain a complex mixture of aliphatic and aromatic hydrocarbons as well as a variety of other compounds. Many of these hydrocarbons have been shown to pose a risk to human health or to aquatic life. Leaking underground storage tanks are a common source of groundwater and soil contamination. It is important to determine the types of hydrocarbons that may be present in contaminated soil and water. This application note describes an automated protocol for the fractionation of EPH into aliphatic and aromatic fractions using the Gilson GX-274 ASPEC™ System.
