Extraction and separation method and apparatus using supercritical fluid

摘要

Extraction and separation method and apparatus using a supercritical fluid for extracting a specified component from a sample by a supercritical fluid and introducing the supercritical fluid containing the extracted component into a silica gel column coated with silver nitrate so as to separate the extracted component.PPBy the combination of the extracting operation by a supercritical fluid under mild conditions and chromatography taking the advantage of the selectivity of the silica gel column coated with silver nitrate to olefins, the extract is obtained at a high concentration without producing denaturation.
