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.
[1][2] 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.
[1] An automated system for the process was developed by Dionex,[3] a company owned by Thermo Fisher Scientific.
[4] The extraction cell is filled with the solid sample to be examined and placed in a temperature-controllable oven.
[5] Accelerated solvent extraction has found many applications in the food industry, including in:
