ABSTRACT:
A biocompatible column for use in liquid chromatography applications includes a biocompatible, polymeric inner tube which is located within a metallic outer tube. The column has biocompatible end fittings which extend beyond the ends of the outer tube. The ends of the outer tube are tapered to extend radially inward towards the longitudinal axis of the column to secure the end fittings and the inner tube in place relative to the outer tube. Alternatively, one or more biocompatible frits are included in seats in the end fittings. A passageway through the inner tube is packed with any one of a number of various packing materials. The present invention may comprise either a guard column or an analytical or preparative column. A liquid chromatography system in which the column of the present invention is used is also described.
