Abstract
A biocompatible column for use in high pressure liquid chromatography applications includes a biocompatible, polymeric inner tube which is located within a metallic outer tube. The polymeric inner tube has end fittings and the inner polymeric tube and such end fittings and comprise a unitary piece. Alternatively, the outside ends of the outer tube may be threaded so that appropriate polymeric end fittings can be removably attached to each end of the column. A liquid chromatography system in which the column of the present invention is used is also shown and described.
