  • Variable potential ion guide for mass spectrometry
    Patent number: 6657190
    Abstract: A variable potential ion guide for placement within the reflectron of a time-of-flight mass spectrometer includes an elongate resistive electrode placed axially within the reflectron. The electrode may be a non-conductive monofilament coated with a resistive polymer coating, with one end of the electrode coupled to a high potential source, the electrode carrying a potential gradient along its length.
    Type: Grant
    Filed: June 20, 2001
    Date of Patent: December 2, 2003
    Assignee: University of Northern Iowa Research Foundation
    Inventors: Curtiss D. Hanson, Paul Trent
