Abstract
A chromatography column distribution system includes a set of first bed support ribs extending radially from an inner, first radial position near the centre of the 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 and extending to an outer radial position nearer to the periphery of the plate. Channels are formed between adjacent bed support ribs. The desired local effective channel height varies in accordance with a predetermined formula from the first radial position to the outer radial position. The transverse cross-sectional areas of the ribs or the 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 the first radial position and the outer radial position. The length of the portions correspond to at least 80% of the distance between the first and outer radial position and the outer radial position.
