Abstract
Abstract A multicartridge chromatography cartridge housing for use in supporting several chromatography cartridges in a parallel array is disclosed. A number of elongated cylindrical cartridge holders extend between a lower support plate and an upper support plate. Each such cartridge holder receives a chromatography cartridge which is held within the holder by suitable end caps and tie rods. Several truss rods serve to space the support plates from each other and to support the housing assembly. Fluid flow manifolds are secured to the lower and upper support plates and serve to distribute the fluid to, and consolidate the fluid received from the cartridges within the individual holders. The multicartridge chromatography cartridge housing in accordance with the present invention handles high fluid flow volumes with a small pressure drop and with a minimum hold up volume.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
121 words
A multicartridge housing for cylindrical chromatographic cartridges, each cartridge effective for the chromatographic separation of a fluid passing radially therethrough, said housing comprising: support means; a plurality of cartridge holders secured to said support means, each of said cartridge holders being structured and sized to surround a cartridge therein and a volume surrounding the cartridge, said volume in fluid communication with said cartridge for radial distribution of the fluid through the cartridge; an inlet fluid manifold means for distributing the fluid being separated to each of said holders for passage of the fluid radially through the cartridges therein; and an outlet fluid manifold means for consolidating the fluid from the holders after passage of the fluid radially through the cartridges therein.
Claim 2
Dependent Claim
121 words
A multicartridge housing for cylindrical chromatographic cartridges, each cartridge effective for the chromatographic separation of a fluid passing radially therethrough, said housing comprising: support means; a plurality of cartridge holders secured to said support means, each of said cartridge holders being structured and sized to surround a cartridge therein and a volume surrounding the cartridge, said volume in fluid communication with said cartridge for radial distribution of the fluid through the cartridge; an inlet fluid manifold means for distributing the fluid being separated to each of said holders for passage of the fluid radially through the cartridges therein; and an outlet fluid manifold means for consolidating the fluid from the holders after passage of the fluid radially through the cartridges therein.
