Abstract

Due to its prominent use in the modern era, petroleum, in one form or another, is ubiquitous commodity. From its primary use as an energy source to its role as an essential feedstock for industry, petroleum’s widespread use leads to instances of uncontrolled releases to the environment.

When an assessment of the affected soil or waters from a spill is required, an effective and comprehensive analytical method should be utilized to make an appropriate decision about the remediation required to mitigate the hazardous nature of the contaminated areas. One such method is the Method for Determination of Extractable Petroleum Hydrocarbons (EPH) contributed by the Massachusetts Department of Environmental Protection. Recognizing the utility of this method, other states such as New Jersey and Texas followed the lead and adopted their own versions based largely upon this work.

The ability to successfully execute such a method requires an SPE cartridge that can discern between two major classes of compounds and depends upon the cartridge’s ability to fractionate cleanly the sample extract for subsequent GC analysis. This ability relies on the properties of the silica as well as the moisture levels in the finished cartridge. The SPE cartridge must also provide a background free of interferences which depends on the cleanliness and lack of leachable materials in the silica and the cartridge components.

This work explores the capabilities of Restek’s Small Bed SPE EPH cartridges to effectively perform the appropriate EPH analytical methods.
