Patents by Inventor Karen C. Waldron

Karen C. Waldron has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Continuous biochemical reactor for analysis of sub-picomole quantities of complex organic molecules
    Patent number: 5565171
    Abstract: A novel reactor for reacting and subsequently analyzing sub-picomole quantities of a sample organic molecule. The reactor includes a continuous capillary connected between two valves that control fluid flow in the capillary. One part of the capillary forms a reaction chamber where the sample may be immobilized for subsequent reaction with reagents supplied through the valves. Another part of the capillary passes through or terminates in the detector portion of an analyzer such as an electrophoresis apparatus, liquid chromatographic apparatus or mass spectrometer. The apparatus may form a peptide or protein sequencer for carrying out the Edman degradation reaction and analyzing the reaction product produced by the reaction.
    Type: Grant
    Filed: May 10, 1995
    Date of Patent: October 15, 1996
    Assignee: Governors of the University of Alberta
    Inventors: Norman J. Dovichi, Karen C. Waldron
