  • Single pass method and apparatus for separating a target molecule from a liquid mixture
    Patent number: 8956535
    Abstract: A single pass simulated moving bed apparatus and methods are described for continuously separating a target molecule from a liquid mixture, using a simulated moving bed system. The simulated moving bed system includes a plurality of filter cartridge modules in serial fluid communication. Each filter cartridge module includes a volume of stationary phase particulates adjacent a porous substrate layer. The volume of stationary phase particulates has a bed height of less than 1 centimeter.
    Type: Grant

  • Analytical device with lightguide illumination of capillary and microgroove arrays
    Patent number: 8268249
    Abstract: An analytical cell including a lightguide with a plurality of conduits filled with a migration medium. The medium, the lightguide and a surrounding medium have refractive indices selected such that light entering the lightguide is internally reflected within the lightguide to provide substantially uniform illumination of the conduits.
