  • Publication number: 20210269888
    Abstract: The present invention relates to a method for optimizing a bioprocess purification system comprising a bioreactor configured to provide a harvest comprising a target composition, and a purification process arranged downstream the bioreactor and being configured for purification of the harvest to produce a target product having a desired characteristics. The method comprising: a) detecting (32) at least one quality attribute indicative of characteristics of the target product in a downstream process, b) identifying (33) correlations between the at least one quality attribute measured in the downstream process and parameters to control a cell culture process in the bioreactor, and c) controlling (34) the cell culture process to meet the desired characteristics based on the identified correlations, whereby the target characteristics is within a pre-determined range.

  • Publication number: 20190346412
    Abstract: The present invention relates to a method for monitoring operational status in continuous chromatography configured to operate with at least three columns adapted for cyclic use for continuous purification of a target product when feeding the continuous chromatography with a sample containing the target product. The method comprises detecting (81) at least one parameter indicative of a selected function in the continuous chromatography, performing (82) real time trend analysis of the detected parameter to identify a deviating behaviour of the selected function, and initiate (83) actions to eliminate or reduce the effect of the identified deviating behaviour where by the performance of the continuous chromatography is maintained.

  • Patent number: 9177417
    Abstract: An implementation of SSP using variable depth for the vectors extending normal to the surface voxels of the brain so as to avoid white matter uptake extraction is provided. The implementation also provides the possibility to compare SSP for an individual amyloid imaging agent image to a SSP normal database and allows for 3D visualization of SSP information.

  • Patent number: 8652322
    Abstract: The invention relates to a multi-component part transducer assembly for determining the pressure of a fluid of interest. One part of the assembly comprises a reusable transducer, another part a disposable component comprising a flexible membrane which is in pressure connection with the fluid of interest, and another part comprises a locking component for securing the reusable and disposable parts together.

  • Patent number: 7896310
    Abstract: A pinch valve is adapted to hold at least one flexible tube in a tube holding room (7) and comprises a plunger (13) adapted to protrude into the tube holding room and pinch the tube against an opposite side wall (11) thereof. The plunger (13) is controllable to be positioned in at least two different positions, an open position where the tube in the tube holding room (7) is not pinched, and a pinching position where the tube is pinched between the plunger (13) and the opposing wall (11). The pinch valve further comprises a tube retaining means (19) adapted to prevent the tube from escaping from the tube holding room (7), especially when the plunger (13) is in the open position, and which can be pivoted into at least two different positions, a non locking position used during insertion of a tube into the tube holding room (7), and a locking position for retaining a tube inside the tube holding room (7) even when the plunger is in an open position.
