The use of ASE in the extraction of OPP compounds from solid wastes is a more convenient, faster, and less solvent-intensive method than previously available. OPP recoveries by ASE are equivalent to recoveries from Soxhlet and other methods. ASE also avoids the problem of multiple washing procedures associated with sonication. This method is applicable to the extraction of water-insoluble or slightly water-soluble organophosphorus pesticides in preparation for gas chromatographic measurements. This method is applicable to soils, solid wastes, and sediments containing 250–2500 μg/kg of OPPs.

The use of ASE in the extraction of chlorinated herbicides from solid wastes is more convenient, faster, and less solvent-intensive than previous methods.U.S. In the method reported in this application note, chlorinated herbicide recoveries by ASE are equivalent to recoveries from the wrist-shaking method recommended in Method 8150A. The procedures described in this application note meet the requirements for sample extraction as prescribed by U.S. EPA Method 3545.

Accelerated Solvent Extraction (ASE) is a new extraction method that significantly streamlines sample preparation. ASE provides a more convenient, faster, and less solvent intensive method than previously available for extraction of PAHs from solid wastes. PAH recoveries by ASE are equivalent to other more solvent intense methods such as Soxhlet or sonication. ASE also avoids the multiple washing procedures associated with sonication. The procedures described here meet the requirements for extraction of PAHs from solid waste in U.S. EPA Method 3545.

Polychlorinated biphenyls (PCBs) belong to a broad family of synthetic organic chemicals known as chlorinated hydrocarbons. In the United States, PCBs were produced from 1929 until their manufacture was banned in 1979.Although all 209 of the PCB congeners can be synthesized, only about 130 individual congeners have been identified in commercial PCB mixtures at concentrations ≥ 0.05%. The method reported here is applicable for the determination of 32 of the 209 possible PCB congeners in soils, including the dioxin-like PCB (“non-ortho”,“mono-ortho PCB”, and “di-ortho PCB”).

Accelerated solvent extraction provides a more convenient, faster, and less solvent intensive method than previously available for the extraction of PAHs from solid wastes. This Application Note updates the work that was done in Thermo Scientific Application Note 313 (AN 313) for the extraction of PAHs from environmental samples. A Thermo Scientific™ Dionex™ ASE™ 350 Accelerated Solvent Extractor system was used for the extraction and Thermo Scientific™ ISQ™ Single Quadrupole GC-MS system to analyze 16 PAHs from soil.
