Patent number: 10955092Abstract: There is provided a method of preparing a mixed liquid having a first property and a second property. The method includes providing a first set of liquids, a second set of liquids, and a third set of liquids. The method includes combining the provided sets of liquids. Further, the method includes varying at least one of the liquid flows of the first and second sets and at least one liquid flow of the third set to adjust the first property and the second property to their respective predetermined values in the resulting mixed liquid flow.Type: GrantFiled: May 5, 2011Date of Patent: March 23, 2021Assignee: Cytiva Sweden ABInventors: Catalin Andrei, Mikael Berg, Torbjorn Blank, Enrique Carredano, Karl Ekstrom, Tomas M.

Patent number: 9327212Abstract: A method for preparing a liquid flow having pre-defined characteristics by mixing liquid flows of at least two different component stock solutions with each other comprises the steps of determining a selected property value for one or more of the stock solutions by sensing, in a flow of each stock solution separately, at least one characteristic related to the property value for the stock solution, and based on the determined property value or values, mixing the stock solution flows in mixing ratios giving the desired mixed liquid flow. A system for carrying out the method comprises sensor means and a control unit, wherein the control unit is arranged to evaluate the characteristics sensed by the sensor means and provide relative ratios of stock solutions required to obtain a mixed liquid flow having the pre-defined characteristics.Type: GrantFiled: September 23, 2010Date of Patent: May 3, 2016Assignee: GE Healthcare Bio-Sciences ABInventors: Torbjorn Blank, Enrique Carredano, Karl Ekstrom, Jan-Erik Lynga, Roger Nordberg, Mike Peters, Gustav Rodrigo, Henrik Sandegren, Lisa Stack

Patent number: 8343349Abstract: A method of maintenance of a chromatography column is described which does not require the use of a hoist or crane for disassembly. The method provides improved operator safety by reducing the need for the operator to work below a suspended or supported load within the column. The provision of guide elements which can be reversibly attached to the column facilitates removal or insertion of column components.Type: GrantFiled: July 17, 2012Date of Patent: January 1, 2013Assignee: GE Healthcare Bio-Sciences ABInventors: Stefan Kjell Eriksson, John Davis, Mats O. Hansson, Kyril Dambuleff, Roger Nordberg

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
