Patent ID: 7452471

Claim:
A method for packing of columns comprising: providing a column packing system with an automated control unit including automation software and hardware; providing said column packing system with a pressure sensor for sensing the column interior pressure, said pressure sensor being adapted to produce a pressure signal, which is able to be monitored by said automated control unit; and/or providing said column packing system with a flow measuring device for measuring fluid flow out of said column, said flow measuring device being adapted to produce a flow rate signal which is capable to being monitored by said automated control unit using said control unit to monitor the movement of a movable adapter in a column containing a consolidated bed of bed media, and one of both of the pressure inside said column and the flow of fluid out of said column; and using said control unit to analyse a pressure signal from said pressure sensor and/or a flow rate signal from said flow measuring device to determine the breakpoint when said movable adapter moves at a constant speed then movable adapter begins to compress said consolidated bed where the consolidated bed is axially compressed, the breakpoint being determined as occurring when there is a decrease in said pressure signal and/or said flow rate signal; and providing said software to calculate the distance that said movable adapter has to move from said breakpoint to achieve the predetermined amount of bed compression and moving said movable adapter to the position corresponding to that distance.
