Abstract
An apparatus for use in liquid chromatography involves a column filled with media bounded axially by first and second porous plates. The column has an inlet end with an inflow region between the inlet end and the first porous plate. The column also has an outlet end with an outflow region between the outlet end and the second porous plate. The inflow region may be substantially longer than the outflow region. The porous plates may be moveable under pressure so as to compress the media.
