Abstract
A chromatography column for effecting chromatographic separation of at least two components of a sample flowing through the column. The column comprises a housing and at least one solid stationary phase within the housing. The stationary phase has chromatographic functionality and is effective for chromatographic separation. Means are provided for radially distributing the sample through the stationary phase and for collecting the sample after the sample has flowed through the stationary phase. The stationary phase comprises: PA1 (a) a swellable fibrous matrix in sheet form having chromatographic functionality and being effective for chromatographic separation, spirally wound around the longitudinal axis of the solid stationary phase to form a plurality of layers around the axis; and PA1 (b) a spacer means between each layer for permitting controlled swelling thereof and enhancing the distribution of sample flowing radially through the stationary phase. The solid stationary phase may be fabricated into a disposable cartridge for placement in the housing. A plurality of cartridges may be used either in series or parallel flow configuration in a single housing.
