AN338: Extraction of Total Petroleum Hydrocarbon Contaminants (Diesel and Waste Oil) in Soils by ASEInstrument Type: Automated Sample Prep
Underground storage tanks containing hydrocarbon-based fuels are found worldwide. Many of these tanks have leaks, allowing gasoline, diesel, oil, or other hydrocarbon materials to contaminate the surrounding soil. Accelerated Solvent Extraction (ASE) is an innovative sample preparation technique to achieve fast and efficient removal of analytes of interest from various matrices. This application note reports on the use of ASE for the extraction of diesel range organics (DRO), waste oil organics (WOO), and total petroleum hydrocarbons (TPH, the sum of DRO and WOO) from soils.
AN317: Extraction of BNAs (Bases, Neutrals, and Acids) Using Accelerated Solvent Extraction (ASE)Instrument Type: Automated Sample Prep
The procedures described in this application note meet the requirements for sample extraction as determined by U.S. EPA Method 3545. This method is applicable to the extraction of water-insoluble or slightly water-soluble volatile and semivolatile compounds in preparation for gas chromatographic or GC/MS measurement. This method is applicable to soils, clays, wastes, and sediments containing 250–12,500 μg/kg of BNA compounds.
