Dionex ASE 200 Accelerated Solvent Extractor

The ASE 200 Accelerated Solvent Extractor is an automated system for extracting organic compounds from a variety of solid and semisolid samples. The ASE 200 accelerates the traditional extraction process by using solvent at elevated temperatures. Pressure is applied to the sample extraction cell to maintain the heated solvent in a liquid state during the extraction. After heating, the extract is flushed from the sample cell into a standard collection vial and is ready for analysis.

ASE is a technique for extracting solid and semisolid samples with liquid solvents. ASE uses conventional liquid solvents at elevated temperatures and pressures to increase the efficiency of the extraction process.

Increased temperature accelerates the extraction kinetics, while elevated pressure keeps the solvent below its boiling point, thus enabling safe and rapid extractions.

ASE can be used to replace Soxhlet, sonication, wrist shaking, and other extraction techniques using less solvent and less time.

Product Highlights
• Extraction time and solvent consumption are reduced by the use of elevated temperature and pressure during extraction.
• Requires less than 15 mL of solvent for a 10-g sample to reduce total solvent usage.
• Extracts are automatically filtered and ready for direct injection or final clean-up.
• 24-position carousel for unattended operation.
• Easy-to-fill sample cells with fingertight fittings.
• Easy-to-use collection vials.
• Convenient multiple method and schedule storage for automatic operation.
• Convenient front panel operation runs methods automatically on up to 24 samples.
• The schedule editor screen lets the operator schedule the extraction conditions and allows the re-extraction of the same cell into separate vials.
• Sensors for temperature, pressure, and solvent leaks alert the operator to a problem, sound an audible alarm, and shut down the system if necessary.
