Method and device for chromatographic separation of components with partial recovery of mixed fractions

The method involves newly positioning junction points between two inlets (45, 46) and two outlets (47, 48) after the running of a cyclic timing unit between two additional chambers or chamber sections of a closed circuit (57). A raffinate flow (43) and/or extract flow (44) discharged by the two outlets are partially and temporarily stored in a temporary storage i.e. tank (62) and is fed alternatively and simultaneously with a multi-component fluid mixture (64) and/or the solvent of chambers (49-52) of chamber sections in the timing unit for the two inlets in a reverse coupling manner. An independent claim is also included for a device for implementing a method for the chromatographic component separation of a multi-component fluid mixture.
