Accelerated solvent extractor

ASE An accelerated solvent extractor ASE-100 from Dionex is used for the treatment of solid samples by what is called pressurized fluid extraction (PLE). This technique is similar to Soxhlet extraction, except that the solvents are used near their supercritical region where they have high extraction properties. The high temperature enables high solubility and high diffusion rate of the analytes in the extraction solvent, while the high pressure keeps this solvent below its boiling point and enables a high penetration of if in the sample.
