CA 2342636

A chromatographic separator allows a feed liquid material consisting of two or more than two components and a liquid eluent to circulate within an endless circular path 16, wherein columns 14 are coupled to one another, to separate the feed liquid material into two components. The selector valves 23 and 33 are switched to allow pumps 20 and 30 to serve to circulate the fluid through the circular path 16 and to inject each liquid from the tanks 25 and 35. Furthermore, an ordinary ON/OFF valve is used as discharge valves 41 and 51 for each of the liquids and thus the pressure specification required for the circular path 1.6 is reduced.

L'invention concerne un séparateur chromatographique qui fait circuler un liquide de matières premières, comprenant au moins deux composants et un éluat, par un trajet de circulation (16) constitué de colonnes (14) montées de façon continue, qui permettent de séparer le liquide de matières premières en deux composants. La commutation entre des vannes de commutation (23, 33) permet à des pompes (20, 30) d'être utilisées à la fois pour la circulation du liquide par le trajet de circulation (16) et pour l'écoulement de différents liquides depuis différents réservoirs (25, 35). Des vannes tout ou rien sont utilisées comme vannes de vidange (41, 51) pour les différents liquides, afin de réduire la pression du trajet de circulation (16).
