Classification: CPC B  C | IPC B  C

Claim 17:
18. The method according to claim 1, wherein:
the volume of the mobile phase injected per cycle is maintained greater than, or equal to, a minimum limit and/or less than, or equal to, a maximum limit, and wherein the method comprises:
the determination, in a node of the system, of the history of a variable that is representative of the concentration of one or more species contained in the mixture to be separated;
wherein the method is such that:
as long as the volume of the mobile phase injected per cycle is greater than, or equal to, said minimum limit, or less than, or equal to, said maximum limit, the method comprises:
the detection on the history of a first characteristic point in area 1;
the detection on the history of a second characteristic point in area 4;
the comparison of the position of each of the characteristic points against a respective target position;
the adjustment of the carrying volume of the area 1 and the carrying volume of the area 4, modifying the position of the first characteristic point and the second characteristic point respectively to bring them closer to their respective target positions;
when the volume of the mobile phase injected per cycle reaches the maximum or the minimum limit, the method comprises:
the detection on said history of a single characteristic point in the portion consisting of area 1, area 4 and the interface between thereof;
the comparison of the position of the characteristic point against a target position;
the adjustment of the carrying volume of the area 1 and/or of the carrying volume of the area 4, modifying the position of the characteristic point to bring the position of the characteristic point closer to the target position.
