Automated packing system and method for chromatography columns

摘要

A column packing system comprises a control unit provided with software for monitoring the column interior pressure and/or flow through the column for use in calculating the breakpoint where a movable adapter comes into contact with a consolidated bed of bed media. The calculated breakpoint is used by the control unit to determine how much further the movable adapter has to move into the column in order to achieve a desired amount of bed compression.

1. A column packing system comprising:
a column having a longitudinal axis, a pressure sensor for sensing a column interior pressure and/or a flow measuring device for measuring liquid flow out of said column, and a movable adapter; said movable adapter being movable while being monitored by a control unit; a compressing means, including automation software and hardware along the longitudinal axis of the column to compress a consolidated bed of bed media in said column to form a compressed packed bed which is compressed a predetermined amount; wherein said control unit is provided with software for monitoring and analysing a signal from said pressure sensor and/or flow measuring device in order to determine a breakpoint when said movable adapter begins to compress said consolidated bed, wherein said movable adapter moves at a constant speed; and wherein said software is adapted to calculate the distance that said movable adapter has to move from said breakpoint to achieve the predetermined amount of bed compression and is able to control the movement of the movable adapter to a position corresponding to that distance; and said breakpoint being determined to occur when there is a decrease in the pressure inside said column and/or a decrease in the flow rate of fluid out of said column
