ABSTRACT:
A chromatographic device in the form of a tube, adapted to contain a bed of particulate adsorbent material, the tube being provided with a removable, gas and liquid permeable, lid at one end and at the other end with a sliding element permeable to liquids and gas and movable within the tube, the sliding element being provided with means to exert a permanent pressure on the bed of particulate adsorbent material so as to maintain it in the form of a solid body during use and to extrude it from the tube when the lid is removed. The device is used to prepare a bed of particulate adsorbent material, to maintain said bed under pressure during use to avoid movement of particles and to extrude the bed after use.
