- Accelerated solvent extraction (ASE) is a method for extracting various chemicals from a complex solid or semisolid sample matrix. The process uses high temperature and pressure, which results in the extraction taking less time and requiring less solvent, and possibly also giving better analyte recovery, than traditional methods that use less extreme conditions. The elevated temperature is employed to increase extraction efficiency of the analyte of interest and the elevated pressure is used to keep the solvent in a liquid state as the temperature is increased above its boiling point. An automated system for the process was developed by Dionex, a company owned by Thermo Fisher Scientific. (en)
- ASE (eng.: Accelerated Solvent Extraction, übersetzt: Beschleunigte Lösemittelextraktion) ist ein Extraktionsverfahren für Inhaltsstoffe fester und halbfester Proben.Die Arbeitsbedingungen unter Druck und bei erhöhten Temperaturen führen zu einer starken Beschleunigung der Reaktionskinetik, zur schnelleren Desorption der Analyte von der Matrix, sowie zu einem beschleunigten Verlauf des Lösungsprozesses insgesamt. Als Lösungsmittel können zum einen organische Lösungsmittel wie Aceton, Pentan oder Ethylacetat, zum anderen auch wässrige Flüssigkeiten (zum Beispiel Pufferlösungen) verwendet werden. Je nach Apparatur können bis zu vier Lösungsmittel kombiniert oder abwechselnd für eine Extraktion verwendet werden. (de)
- L’extraction par liquide pressurisé (pressurized liquid extraction, PLE), aussi appelée extraction par solvant accélérée (accelerated solvent extraction, ASE) ou extraction par fluide pressurisé (pressurized fluid extraction, PFE) est une technique d'extraction solide-liquide. Elle utilise des solvants organiques ou aqueux à températures et pressions élevées afin d’extraire des composés d’un échantillon solide ou semi-solide. Cette technique a été introduite en 1995 afin de remédier à certaines inquiétudes associées aux techniques d'extraction solide-liquide classique qui utilisent des quantités importantes de solvants et nécessitent un temps d’exposition notable pour les expérimentateurs. Elle fut rapidement adoptée dans les laboratoires puisqu’elle a l’avantage d’effectuer des extractions beaucoup plus rapides en utilisant moins de solvant. (fr)
- L'estrazione accelerata con solvente o estrazione pressurizzata, indicata con le sigle PSE o ASE (dall'inglese Pressurized Solvent Extraction o Accelerated Solvent Extraction), è una tecnica di estrazione solido-liquido. Si utilizza un solvente in condizioni sub-critiche (da non confondere con l'estrazione con fluido supercritico), sotto pressione e ad alte temperature per estrarre in fase liquida l'analita o gli analiti dalla matrice solida. Rispetto alle tecniche di estrazione solido-liquido tradizionali questa tecnica consente di ridurre la quantità di solvente necessario, di ridurre i tempi di estrazione e si presta meglio all'automazione del processo. Si fa in recipienti chiusi e termostatati. (it)
