Claim Text:
1. A chromatography column distribution system comprising a set of first bed support ribs having an elongated rib body characterized by a width extending radially from an inner, first radial position near the center of a plate to an outer radial position nearer to the periphery of the plate and at least one set of intermediate bed support ribs starting at an intermediate radial position of the plate and extending to an outer radial position approximately near the periphery of the plate, wherein channels are formed between adjacent bed support ribs and at least one elongated rib body width is intended to vary in accordance with a predetermined formula from said first radial position to said outer radial position for minimizing local throttling and local pressure increases, and wherein the transverse cross-sectional areas of said support ribs or said channels are adapted such that the actual local effective channel height is within 15% of the desired local effective channel height over portions of the distribution system situated between said first radial position and said outer radial position, wherein the total length of said portions correspond to at least 80% of the distance between said first radial position and said outer radial position.
