An apparatus for use in liquid chromatography involves a column filled with media bounded axially by at least one porous member. The column has an inlet end with an inflow region between the inlet and a porous member. The inflow region may be sufficiently long so that a chromatography sample module may be disposed therein. The column may be sufficiently long so that a chromatography sample module may be disposed therein. The column may also have an outlet end with an outflow region between the outlet end and a second porous member. The inflow region may be substantially longer than the outflow region. The porous members may be moveable relative to the column.
