Accelerated Solvent Extraction (ASE®)

Accelerated Solvent Extraction (ASE)

OverviewIn-Cell Cleanup Tired of spending days on sample preparation? Tired of spending countless hours on labor-intensive sample preparation steps?

Accelerated Solvent Extraction (ASE®) is a patented technique for the extraction of solid and semisolid sample matrices using common solvents at elevated temperatures and pressures. ASE systems are available in the entry-level ASE 150 system, and fully automated ASE 350.

Extractions that normally take hours can be done in minutes using ASE with pH hardened pathways using Dionium™ components. Compared to techniques such as Soxhlet and sonication, ASE generates results in a fraction of the time.

The many steps involved in sample preparation can now be automated with ASE flow-through technology. Filtration and clean-up of solid samples can be achieved as part of the solvent extraction process in a single step. ASE offers a lower cost per sample than other techniques, reducing solvent consumption by up to 90%.

Benefits

  • Extractions for sample sizes 1-100 g in minutes
  • Dramatic solvent reduction
  • Wide range of applications
  • Handles acidic and alkaline matrices
  • Approved for use by the U.S. EPA and CLP Program

Dionex ASE systems can be applied to many industries
