Abstract
Improved liquid chromatographic apparatus and an improved process for making and utilizing a chromatographic column. By providing means to exert radial pressure on the column packing, the packing efficiency of the column is increased and is more reproducible, and greater uniformity can be achieved in column performance both among packed columns of the same kind and during the useful life of a given packed column.
