AN319: Extraction of Organophosphorus Pesticides Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

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.

AN343: Determination of Pesticides in Large-Volume Food Samples Using Accelerated Solvent Extraction (ASE)

Instrument Type: Automated Sample Prep

Accelerated Solvent Extraction (ASE) is an extraction technique that speeds the extraction process and reduces the total amount of solvent used. The system uses conventional solvents at elevated temperatures and pressures, which results in improved extraction kinetics. The Dionex ASE 300 has the capability to extract samples with volumes as large as 100 mL. This application note reports on the use of the ASE 300 for the determination of organophosphorus pesticides (OPPs) in fruits and vegetables.
