<p>The rotary member (12) of the rotary valve (10) includes columns (separation vessels) (14) coupled to each other to form an endless circular path (16) and rotates to separate components A and C from a feed liquid material containing two or more components. A concentration sensor (17) is connected to a tube (141) that connects between columns (14) and is mounted on the rotary member (12) rotatably in unison with the columns (14) to detect the concentration of the component A flowing in the circular path (16). Based on the detected result of the concentration sensor (17), fine tuning of the timing of start and the time length of each step can be effected, thereby providing an improved separation performance for the chromatographic separator. <IMAGE></p> |
