Solvent extractions that normally require labor-intensive steps are automated or performed in minutes, with reduced solvent consumption and reduced sample handling using Accelerated Solvent Extraction (ASE^®) or AutoTrace^® systems.

ASE systems use a patented technique for the extraction of solid and semisolid samples using common solvents at elevated temperature and pressure. The ASE 150 and 350 systems feature pH-hardened pathways with Dionium™ components to support extraction of acidic or alkaline matrices, and combine pretreatment, solvent extraction, and cleanup into one step. Dionium is zirconium that has undergone a proprietary hardening process that makes it inert to chemical attack by acids and bases at elevated temperatures.

ASE systems are dramatically faster than Soxhlet, sonication, and other extraction methods, and require significantly less solvent and labor. ASE methods are accepted and established in the environmental, pharmaceutical, foods, polymers and consumer product industries. ASE method are accepted and used by government agencies worldwide.

The AutoTrace 280 instrument performs automated solid-phase extractions (SPE) of large volume liquid sample matrices. The instrument automates the standard SPE steps of condition, load, rinse, and elute to reduce sample handling and improve productivity. AutoTrace systems are available in cartridge or disk formats, and can be used for numerous US EPA methods requiring extraction prior to analysis.
