Accelerated Solvent Extraction is a technique for extracting solid and semisolid samples with liquid solvents. ASE uses conventional liquid solvents at elevated temperatures and pressures to increase the efficiency of the extraction process. Increased temperature accelerates the extraction kinetics, while elevated pressure keeps the solvent below its boiling point, thus enabling safe and rapid extractions. This method is allows us to perform in minutes what normally might take hours.

Some details
  • We extract at 100°C, 1000 psi with a mixture of 9:1 methanol:dichloromethane
