Abstract
A simulated moving-bed type chromatographic separation method separating a weakly adsorptive component, a strongly adsorptive component, and an intermediately adsorptive component, with eluents by using a circulation system in which a plurality of unit packed columns packed with an adsorbent are connected in series and in an endless form via pipes in which a feed solution supply port F, two or more eluent supply ports D corresponding to the eluents, an extraction port A of a fraction containing the weakly adsorptive component, an extraction port B of a fraction containing the intermediately adsorptive component, and an extraction port C of a fraction containing the strongly adsorptive component are provided in the pipes of the circulation system, and positions of the ports F, A, B, and C are set to have a specified relationship.
