ABSTRACT:
A method of rapid chromatographic separation by exchange of substances between two fluid phases circulating in coutercurrent flow, at least one phase being liquid, consists in injecting the substances to be separated into one of the phases, in causing the two phases to circulate on each side of a porous body having a thickness within the range of 1 to 200 microns while limiting the thickness of at least one liquid phase to a constant value within the range of 0.1 to 100 microns and in collecting after circulation the substances which have been separated in each of the two phases.
