  • Patent number: 9511336
    Abstract: The present invention relates to a method for producing beads comprising a material capable of gelation, said method comprising the steps of: (i) combining (a) a liquid composition comprising a material capable of gelation; and (b) a first hydrophobic phase; (ii) subjecting the liquid composition and the first hydrophobic phase, to means for emulsification in a first reactor by addition of external mechanical energy creating an emulsion comprising individual droplets comprising the material capable of gelation in the first hydrophobic phase (wherein the material capable of gelation provides a discontinuous phase and the first hydrophobic phase provides a continuous phase); (iii) stabilizing the droplets by transferring the emulsion from the first reactor to a stabilization reactor wherein the emulsion obtained in step (ii) is subjected to means for gelation in order to obtain gelation within 5 minutes or less, and the beads are formed.

  • Patent number: 9220997
    Abstract: In the field of expanded bed adsorption chromatography, with particular but not exclusive relevance to disposable expanded bed chromatography columns, a method of conducting upward flow expanded bed chromatography comprising: supplying a liquid via an inlet to a stationary phase medium contained in a column, allowing adsorption of at least one component from the liquid by the stationary phase medium, withdrawing the liquid from the column via an outlet, regulating the expansion of the stationary phase medium by regulation of the flow rate of the liquid through at least the inlet, and restricting any overpressure in the headspace of the column to not more than the outside pressure plus 0.1 bar, is provided. In addition, apparatus for use in said method, in particular columns for use in expanded bed chromatography, are provided.
