摘要
A preparative chromatography column is equipped with one or more valves that can each be used to both inject a column packing into the column or withdraw used packing from the column, in addition to cleaning the supply and discharge lines associated with the valve itself, all by moving a movable plug within the valve body and all without protruding into the column interior. Each valve is mounted on the lateral wall of the column just above the filter plate at the column floor, and the plug is movable between a closed position in which the end surface of the plug is flush with the inner wall of the column and an open position in which the plug is recessed within the bore. Each valve has two additional ports in its valve body, positioned such that when the plug is closed, both ports are open to the valve bore, and when the plug is open, at least one of the ports is open to the bore. The position of the plug within the valve bore determines the valve function.
