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:

Environmental

• Pesticides and herbicides
• PAHs and semi-volatiles
• PCBs
• Dioxins and furans
• TPH (DRO)
• Explosives
• Air sampling cartridges (XAD and PUFs)
• Brominated flame retardants

ASE 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.

In-Cell Cleanup

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:
