Solvent extractions that normally require labor-intensive steps are automated or performed in minutes, with reduced solvent consumption and reduced sample handling using the Thermo Scientific™ Dionex™ ASE™ Accelerated Solvent Extractor system or Thermo Scientific™ Dionex™ AutoTrace™ 280 Solid-Phase Extraction instrument.
Dionex ASE systems use a patented technique for the extraction of solid and semisolid samples using common solvents at elevated temperature and pressure. The Dionex 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.
Dionex ASE systems are dramatically faster than Soxhlet, sonication, and other extraction methods, and require significantly less solvent and labor. Accelerated solvent extraction methods are accepted and established in the environmental, pharmaceutical, foods, polymers and consumer product industries. Accelerated solvent extraction methods are accepted and used by government agencies worldwide.

The Dionex AutoTrace 280 SPE 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. The Dionex AutoTrace 280 system is available in cartridge or disk formats, and can be used for numerous U.S. EPA methods requiring extraction prior to analysis.

The Thermo Scientific Dionex AutoTrace 280 Solid-Phase Extraction instruments reduces labor and solvent consumption by up to 90% when compared to traditional liquid extraction techniques. The Dionex AutoTrace 280 instrument automates the SPE process to provide high sample throughput combined with reliable analytical results.
In preparative chromatography the goal is to isolate a large quantity of organic target molecules during each run. Dionex demonstrates how the deficiency of a limited mass loading capacity can be overcome by using adaptable and sophisticated sample injection procedures.
Dionex offers solutions for IC Sample Preparation with AutoPrep and RFIC-ESP.
