CA 2255048

A chromatography cartridge assembly (12) includes a cartridge (22) with flexible wall defining a chamber, and porous, polymeric, hydrophilic, chromatography media contained within the chamber. The chromatography media have an operating pressure greater than 3 bars. The flexible wall has a moving diaphragm for compressing the chromatography media. The chromatography cartridge assembly (12) includes a flow distributor, flow collector, and sieves formed from a hydrophilic material. A compression module (20) defines a pressure chamber for containing a pressurized fluid. The pressurized fluid acts to move the flexible wall of the cartridge assembly (12). The compression module (20) has a pressure rating greater than 3 bars.

Cet ensemble cartouche (12) de chromatographie comprend une cartouche (22) dotée d'une paroi flexible délimitant une chambre, ainsi qu'un milieu de chromatographie, hydrophile, polymère et poreux, contenu dans cette chambre. Ce milieu de chromatographie possède une pression de fonctionnement supérieure à 3 bars. La paroi flexible est pourvue d'un diaphragme mobile destiné à comprimer le milieu de chromatographie. Cet ensemble cartouche (12) comprend également un répartiteur d'écoulement, un collecteur d'écoulement, ainsi que des tamis formés à partir d'un matériau hydrophile. Un module de compression (20) délimite une chambre sous pression destinée à contenir le fluide sous pression, lequel agit pour déplacer la paroi flexible de l'ensemble cartouche (12). Ce module de compression (20) présente une pression nominale supérieure à 3 bars.
