Provided herein in some embodiments is a column including a housing assembly and a cartridge assembly. The housing assembly can include a housing top, a housing bottom, and a housing siding. The housing siding can be fixedly coupled to the housing top and the housing bottom forming hermetic seals therebetween. The cartridge assembly can include a cartridge top, an outer frit, and an inner frit disposed within the outer frit. A toroidal space can defined by the cartridge top, the outer frit, the inner frit, and the housing bottom. The toroidal space can be configured to hold a stationary phase for radial flow column chromatography. Also provided herein in some embodiments is a process including assembling the cartridge assembly, assembling the housing assembly about the cartridge assembly, and pressure testing the column. In some embodiments, the process can further include charging the toroidal space with a stationary phase.

Pre-packed, sealed radial flow chromatography column

A method, apparatus, and system are described to pack and unpack resin in a chromatography-column. One or more inflatable seals are deflated to pack a resin slurry from a bottom outlet valve into a resin bed chamber located between an outer shell of the column and an inner frit of the chromatography-column. The resin slurry is pumped into and through an outlet packing-and-running port and passed one or more deflated inflatable seals to pack the resin bed to a designated pressure with resin slurry. The inflatable seals are inflated to seal the resin bed in place.
