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.
