Patent

CA 2348298

This application comprises a liquid chromatographic system comprising units selected from: a) a block (4) for distributing a liquid flow to a vessel (8), the characteristics being that there are through passing channels (7) comprising a narrow part (7a) and a widening part (7b), optionally with one check valve function per channel; b) a predistributor comprising a network of pipes starting at a pump (1), the characteristics being that the branches are narrowing down when going from the pump to the end pipes (3), and that each end pipes (3) have constriction means (19) providing for a significant pressure drop; c) a distributor with a distributor chamber (9) having an inlet pipe (11) equipped with spinkler means (20); d) a tiltable chromatographic vessel (8) having a valve (15, 42) in its top and being possible to tilt 180~ thereby facilitating emptying through the valve; the individual subunits and their use are also claimed.

L'invention porte sur un système chromatographique liquide comprenant des unités sélectionnées à partir de: a) un bloc (4) de distribution de liquide s'écoulant vers un réceptacle (8), ce bloc se caractérisant par des canaux (7) traversants comprenant une partie (7a) étroite et une partie (7b) plus large, chaque canal étant éventuellement pourvu d'une fonction clapet; b) un prédistributeur comprenant un réseau de tuyaux partant d'une pompe (1) et se caractérisant en ce que les ramifications rétrécissent en allant de la pompe aux tuyaux (3) terminaux, et en ce que chaque tuyau (3) terminal comporte un dispositif (19) d'étranglement générant une chute de pression importante; c) un distributeur pourvu d'une chambre (9) de distribution possédant un tuyau (11) d'amenée doté d'un dispositif (20) de pulvérisation; d) un réceptacle (8) chromatographique inclinable pourvu d'une valve (15, 42) dans sa partie supérieure et pouvant s'incliner de 180· de façon à faciliter la vidange par la valve. Les sous-unités individuelles et leur utilisation sont également revendiquées.
