摘要

P describes a method and apparatus of the characterization of a parameter relative to the organic material which can be extracted by at least one solvent in the temperature and pressure conditions for supercritical. & br / according to the invention, it is made to circulate the solvent in a closed circuit, and carries out the extraction of the sample at a temperature and at a pressure of at least equal to the critical temperature and to the critical pressure of the solvent, so as to produce a solution of extract comprising at least one molecule of organic material, the measurement is made of said parameter from said molecule, and it is produced from this measurement at least a signal representative of said parameter relating to the organic material, said measurement being carried out substantially to the temperature and pressure of the extraction. & br / application in particular to the organic geochemistry. & br / (see appended drawing in bopi) & br / & & br / / p
