A method for conducting maintenance on a chromatography column comprises providing a column having a dispersion system, and a tube 612 with an adapter assembly (415, fig 5a) connected to an integrated drive system. The adapter assembly comprises backing plate (364, fig 5a), distributor (366, fig 5a) and a bed support 628 fastened to each other by releasable fixing means. The adapter assembly is lifted above the tube using the drive system to provide a gap for access. Guide elements, such as rails 690, are affixed to the tube, and the bed support is unfastened and removed for maintenance, without accessing the interior of the column. Preferably, the guide elements are attached to a cross member 686 of a trolley or cart. The bed support is then returned to the column, the guide elements released from the tube, and the adapted assembly lowered to an operational position within the tube. The method does not require the use of a hoist or crane for disassembly.
