Abstract
A simulated moving-bed type chromatographic separation method including separating a weakly adsorptive component, a strongly adsorptive component, and an intermediately adsorptive component that has adsorptive property intermediate between the two components, with respect to an adsorbent, with two or more kinds of eluents by using a circulation system in which a plurality of unit packed columns each packed with an adsorbent are connected in series and in an endless form via pipes, the weakly adsorptive component, the strongly adsorptive component, and the intermediately adsorptive component being contained in a feed solution, wherein a feed solution supply port, eluent supply ports and a plurality of extraction ports are provided on the pipes of the circulation system, and positions of the feed solution supply port and the plurality of extraction ports are set to have a specified relationship; and a chromatographic separation system suitable for implementing the chromatographic separation method.
