Abstract
The invention concerns a method for separating fractions of a mixture to be separated, in a device (1) comprising: several chromatography columns (21, 22, 23,) mounted in series; an open separation loop comprising in input a point for injecting (6) eluent in one of the columns and in output a point for drawing (8) a fraction of the mixture. The method includes the following steps: batch injection of the mixture to be separated in the open separation loop (4); collecting at least two fractions; offsetting at least one column of the eluent injecting and fraction drawing points (6, 8) of the separation loop (4). The invention also concerns a device for separating fractions of a mixture to be separated.
