  • Mixing apparatus and method
    Patent number: 6874928
    Abstract: Apparatus for mixing a number of components comprising a vessel for receiving the components, drive means for rotating or oscillating the vessel about an axis to effect mixing of the components within the vessel, and at least one spectroscopic monitoring means for repeatedly scanning the mixture to obtain data for use in monitoring changes in the spectroscopic profile of the mixture as mixing proceeds, the monitoring means by mounted off-axis relative to the axis about which the vessel is rotatable or oscillatable.
    Type: Grant
    Filed: March 3, 2004
    Date of Patent: April 5, 2005
    Assignee: Astra Zeneca U.K. Limited
