Abstract

A chromatographic column is disclosed in which flow through the separating medium bed takes place horizontally. The column is packed with small, rigid, high performance separation medium. The fluid sample containing several components flows horizontally through the stationary phase or medium and is separated at least partially into discrete components. Means for providing even horizontal flow distribution of the sample fluid and for collection of the discrete components of the sample fluid are included. The stationary phase consists of a packed bed of high performance, small size particles of either (a) absorbants such as silica, alumina etc; (b) packing for reverse phase ion-exchange, affinity, hydrophobic, chiral or ion chromatography; (c) hydroxylapatite; or packing used for desalting. The column as a whole may be fabricated to be disposable or may be constructed to have a more simplified but durable housing.
