Publication number: 20210394083Abstract: A method for packing a media bed in a column (3). According to the invention the method comprises the steps of: providing data to a control unit (15) connected to the column (3), said data comprising at least a measured slurry concentration, a target bed height, a target packing factor or compression factor and minimum and maximum acceptable values for at least one of target bed height and target packing or compression factor; forcing a movable adapter (9) along a longitudinal axis of the column (3) in order to pack the media; detecting when the media bed is consolidated; the control unit (15) processing the provided data and the information about the consolidated bed height in order to present to the user acceptable bed heights, if there are any, giving acceptable packing or compression factors.Type: ApplicationFiled: September 1, 2021Publication date: December 23, 2021Inventors: Per Karlberg, Erik Rurling, Joakim Lundkvist

Patent number: 8133395Abstract: A method for automatically without any required manual interaction packing a media bed in a column (3) from a slurry being a dispersion of said media particles and a liquid, said method comprising the steps a)-f) which all are performed automatically: a) filling the column (3) with a certain volume of slurry; b) packing a media bed from the slurry to a predefined target bed height or a predefined target bed compression; c) testing the separation efficiency of the packed bed; d) automatically unpacking the bed if test results not are acceptable or alternatively flow conditioning the packed bed if test results not are acceptable and return to c); e) calculating new volume of slurry to be filled into the column based on the test results; f) repeat from a).Type: GrantFiled: May 26, 2009Date of Patent: March 13, 2012Assignee: GE Healthcare Bio-Sciences ABInventors: Johan F. Karlsson, Joakim Lundkvist

Publication number: 20110100932Abstract: A method for handling separation media slurry in a tank, before transferring the separation media slurry to a column or a container. The method comprises the steps of: —blowing gas from the bottom of the tank into the sedimented media in the tank and thereby the sedimented media starts to re-suspend; —starting an impeller (7) provided in the tank in order to stir said media slurry that already has started to re-suspend.Type: ApplicationFiled: June 4, 2009Publication date: May 5, 2011Applicant: GE HEALTHCARE BIO-SCIENCE ABInventors: Tom Lonnqvist, Roger Nordberg, Joakim Lundkvist
