An Automated Method for the Fractionation of Extractable Petroleum Hydrocarbons (EPH) from Water and Soil Extracts
1 Oct 2017Crude 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.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Soil TestingSoil testing helps determine the nutrient content, pH level, and other factors affecting soil health. This information is critical for agriculture, environmental science, and land management.
