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.

l'ensemble tournant (12) d'une soupape rotative (10) tourne cependant que des colonnes(14) montées sur l'ensemble tournant (12) et reliées à un chemin à circulation sans fin assurent la séparation de constituants A et C d'une matière liquide renfermant au moins deux constituants. Un détecteur de concentration (17) inséré dans un conduit (141) entre deux colonnes (14) est monté sur l'ensemble tournant (12) de manière à tourner avec les colonnes (14) et à détecter la concentration du constituant A dans le chemin à circulation. On fixe avec précision le moment du démarrage et le laps de temps écoulé ultérieurement pour chaque opération en fonction des résultats du processus de détection fourni par le détecteur de concentration (17) afin d'améliorer les caractéristiques marche du dispositif de séparation chromatographique.
