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%.
