Method and apparatus for the characterization of organic material extractable by at least one solvent under conditions of supercritical temperature and pressure

摘要

Method and apparatus for characterising a parameter relating to organic material capable of being extracted by at least one solvent under supercritical temperature and pressure conditions. The solvent is circulated in a closed circuit and performs the extraction of the sample at a temperature and pressure which are at least equal to the critical temperature and the critical pressure of the solvent, so as to produce one extract solution containing at least one molecule of organic material, the said parameter is measured by starting with the said molecule and from this measurement at least one signal is produced, representing the said parameter in relation to the organic material, the said measurement being performed substantially at the said extraction temperature and pressure.
