The adsorbent bed (25) retained in an HPLC column (1) is maintained in a constant state of compression by a spring loaded hydraulically active second column (13). A relatively small spring (14) loaded piston (15) in the second column maintains a constant hydraulic pressure in the hydraulic chamber (3) of the larger diameter HPLC column (1). Multiple small diameter columns (13) can be employed if necessary.
