    摘要： A method of chromatography in which a chromatograph having a circulation system comprising unit packing layers (1) to (4) endlessly connected in series is used for separating three ingredients A, B, and C whose affinity for the packing is in the order of C>B>A, which comprises a step (1) as the first stage in which the following operations } } } } are conducted and a subsequent step (2) as the second to fourth stages which comprises three repetitions of the following operations } } , the liquid introduction point and the liquid discharge point each being shifted by one unit layer toward the downstream side in the circulation system after every stage: the circulation system is interrupted, and all the ingredient B fraction is discharged from the upstream side of the interruption point while supplying a feed fluid f to the unit packing layer on the immediately downstream side of the interruption point and further supplying an eluent D to the circulation system; the ingredient A fraction is partly discharged while supplying the eluent D to the circulation system; the ingredient C fraction is partly discharged while supplying the eluent D to the circulation system; and liquid circulation is conducted through the circulation system without conducting liquid supply to the system or liquid discharge therefrom.

    摘要： The invention concerns a method for separating at least a constituent of a mixture in a set of looping chromatographic columns, the loop comprising at least a point for injecting a load, a point for drawing off the raffinate, a point for injecting an eluting agent and a point for drawing of the extract. The method consists in: determining between an injection point and a drawing off point or vice-versa a chromatographic zone and at the end of a specific time interval, the whole set of injection points and drawing off points are offset by the same number of columns or column sections and advantageously from one column or one column section in a specific direction defined with respect to that of the flow of the main fluid circulating through the loop. During said time interval, the offsetting of the different injection and drawing off points of at least one column or column section is carried out at different times such that the length of the zones defined by the different points varies. The invention is useful in particular for separating stereoisomers for pharmaceutical purposes.
