VOLATILE ELUENT PREPARATION
(FR)
PRÉPARATION D'ÉLUANT VOLATIL
Abstract:
(EN)
There is provided a system for performing a chromatographic separation of an analyte, methods of using the system to separate at least one component of an analyte and an eluent generator of use in the system. An exemplary system comprises: (a) an eluent generator comprising: (i) a housing configured to be pressurizable by gas, comprising an annular void defined by the housing, and a gas inlet for the gas and a gas outlet for the gas in fluid communication with the annular void; (ii) a membrane permeable to the gas defining an eluent flow channel disposed within the annular void, the eluent flow channel having an eluent precursor fluid inlet and an eluent outlet; (iii) a source of gas in fluidic communication with the gas inlet; (iv) a source of the eluent precursor fluid; and (b) a chromatography column disposed downstream of and in fluidic communication with the eluent outlet.
(FR)
L'invention concerne un système destiné à réaliser une séparation chromatographique d'une substance à analyser, des procédés d'utilisation du système afin de séparer au moins un composant d'une substance à analyser, et un appareil de production d'éluant utilisé dans le système. Un système donné à titre d'exemple comprend : (a) un appareil de production d'éluant comprenant : (i) un boîtier conçu pour pouvoir être mis sous pression par du gaz, comprenant un vide annulaire défini par le boîtier et une entrée de gaz pour le gaz et une sortie de gaz pour le gaz en communication fluidique avec le vide annulaire ; (ii) une membrane perméable au gaz définissant un canal de circulation d'éluant disposé dans le vide annulaire, le canal de circulation d'éluant ayant une entrée de fluide précurseur d'éluant et une sortie d'éluant ; (iii) une source de gaz en communication fluidique avec l'entrée de gaz ; (iv) une source du fluide précurseur d'éluant ; et (b) une colonne de chromatographie disposée en aval de la sortie d'éluant et en communication fluidique avec celle-ci.
