  • Chromatographic and electrophoretic separation of chemicals using electrically conductive polymers
    Patent number: 6821417
    Abstract: A separation system comprising a stationary phase, a double stranded conductive polymer system contacting the stationary phase and means to place a mobile phase carrying a component to be separated from the mobile into contacting relationship with the polymer system whereby the component is captured by the polymer. The double stranded polymer is comprised of a -conjugated polymer and a polyelectrolyte.
    Type: Grant
    Filed: July 9, 2002
    Date of Patent: November 23, 2004
    Assignee: The Board of Governors, State of Rhode Island and Providence Plantations
