Accelerated Solvent Extraction
Tired of spending days on sample preparation? Tired of spending countless hours on labor-intensive sample preparation steps?
Accelerated solvent extraction is a patented technique for the extraction of solid and semisolid sample matrices using common solvents at elevated temperatures and pressures. Thermo Scientific Dionex ASE systems are available in the entry-level Dionex ASE 150 system, and fully automated Dionex ASE 350.
Extractions that normally take hours can be done in minutes using accelerated solvent extraction with pH hardened pathways using Dionium™ components. Compared to techniques such as Soxhlet and sonication, accelerated solvent extraction generates results in a fraction of the time.
The many steps involved in sample preparation can now be automated with accelerated solvent extraction flow-through technology. Filtration and clean-up of solid samples can be achieved as part of the solvent extraction process in a single step. Accelerated solvent extraction offers a lower cost per sample than other techniques, reducing solvent consumption by up to 90%.
- 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 Accelerated Solvent Extractor systems can be applied to many industries:
- Pesticides and herbicides
- PAHs and semivolatiles
- Dioxins and furans
- TPH (DRO)
- Air sampling cartridges (XAD and PUFs)
- Brominated flame retardants
Accelerated solvent extraction meets all of the requirements for extraction under U.S. EPA SW-846 Method 6860 Method 3545A for Pressurized Fluid Extraction, and is accepted under CLP SOW OLMO4.2.

The Dionex ASE 150 system is an entry level system for laboratories with modest throughput. The Dionex ASE 350 system is a sequential extraction system capable of automated extraction of up to 24 samples.
Dionex offers ASE accessories to improve productivity and allow sample tracking.
Thermo Scientific™ Dionex™ ASE™ Accelerated Solvent Extractor parts and accessories are designed and manufactured to meet the unique specifications of the Dionex ASE systems and meet the quality requirements of modern analytical laboratories.
Concentration and evaporation is an important step in achieving accurate analytical results with sample extracts. It is also labor intensive. The Thermo Scientific™ Rocket™ Evaporator automates this process, allowing the analyst to spend more time on other projects.
ASE® systems are designed to combine important sample prep tasks such as extraction, filtration, and cleanup to streamline the sample preparation process. Flow-through extraction allows absorbents to be added directly to the ASE extraction cell to remove interferences, for one-step extraction and cleanup.
- May eliminate GPC or other post-extraction cleanup steps.
- Reduces process time by performing cleanup and extraction simultaneously.
- Increases total sample preparation throughout—not just the number of samples extracted.
Absorbents for use in removing interferences from specific analyte groups include:
Nonpolar compounds, dioxins
Organics, metals, and ionic interferences
Anions, cations, metal speciation (arsenic)
Organics, lipids, chlorophyll
Acid impregnated silica gel
Lipids and oils
PCB and brominated flame retardants
Lipids, chlorophyll, petroleum, waste
Amines, perchlorates, and PCB’s
Oils, lipids, and waxes
Pesticides and aromatics
