Title
(EN) VARIABLE LOAD CHROMATOGRAPHY VALVE FOR FLUID ANALYSIS
(FR) VANNE DE CHROMATOGRAPHIE À CHARGE VARIABLE DESTINÉE À UNE ANALYSE DE FLUIDE
Abstract
(EN) A chromatography valve for use in fluid analysis and chromatography applications is provided. The valve includes a first body having passages extending therethrough and opening on a flat face of the first body at respective passage ports. The valve also includes a second body engaged with the first body in a sealed relationship, whereby one of the first and second bodies is movable relative to the other one between two or more positions for controlling fluid circulation through the passages. The second body includes at least one cartridge receiving cavity for receiving at least one cartridge removably provided therein. The cartridge has channel(s) for channeling fluid of pairs of the passage ports, depending on the position of the first body relative to the second body, thereby channeling fluid through selected ones of the passages via the at least one channel. A method of operating the valve is also provided.
(FR) L'invention concerne une vanne de chromatographie destinée à être utilisée dans des applications d'analyse de fluide et de chromatographie. La vanne comprend un premier corps possédant des passages s'étendant à travers lui et s'ouvrant sur une face plate du premier corps au niveau d'orifices de passages respectifs. La vanne comprend également un second corps en prise avec le premier corps dans une relation étanche, l'un des premier et second corps étant mobile par rapport à l'autre entre au moins deux positions afin de commander la circulation de fluide à travers les passages. Le second corps comprend au moins une cavité de réception de cartouche destinée à recevoir au moins une cartouche disposée amovible dans la cavité La cartouche possède un ou plusieurs conduits permettant de conduire un fluide de paires des orifices de passage, en fonction de la position du premier corps par rapport au second corps, ce qui permet de conduire un fluide à travers les passages sélectionnés par l'intermédiaire dudit au moins un conduit. L'invention concerne également un procédé d'actionnement de ladite vanne.
