Abstract
The liquid chromatographic column (LCC) in liquid chromatography apparatus (LCA) is connected to another fluid flow member, e.g., an injection valve and/or a detector, via a column retainer that comprises a collet with split, tapered distal end that threads into a collet nut having an internal tapered lumen to cause the collet split end to compress about the outside of the liquid chromatographic column so that the retainer assembly may hold the column without damage to it in connected position with the other fluid flow member. The column retainer may include a retainer nut that serves to hold the retainer assembly onto the fluid flow member by threading into a female opening in it.
