  • CHROMATOGRAPHY COLUMN WITH LOCKED PACKED BED AND METHOD OF PACKING THAT COLUMN
    Publication number: 20200289957
    Abstract: A chromatography column has a retaining plug permanently fixed to an upstream end of the column and blocks one end of the bore through the column. The plug has a fluid passage therethrough. An upstream end of the passage is preferably but optionally larger in diameter than a downstream end of the passage. An upstream porous member upstream of the retaining plug is held by an upstream end cap and urged toward the plug. Chromatographic media extends from the upstream porous member, through the passage in the retaining plug, to a downstream porous member held by a downstream end cap. The media between the retaining plug and the downstream porous member are under compression to form a bed of packed media.
