ABSTRACT:
In a chromatographic column assembly comprising a tubular column a first end of which is sealed, the second end of said column is also sealed in order to form an enclosure between said second end and a piston. A pressurized fluid introduced into this enclosure displaces the piston in the direction corresponding to compression of a packing or filling provided in the column. A flexible conduit ensures the circulation of a fluid to be chromatographed and crosses through the piston, the enclosure containing the pressurized fluid and the second end of the column.
