  • Means of introducing an analyte into liquid sampling atmospheric pressure glow discharge
    Patent number: 10269525
    Abstract: A liquid sampling, atmospheric pressure, glow discharge (LS-APGD) device as well as systems that incorporate the device and methods for using the device and systems are described. The LS-APGD includes a hollow capillary for delivering an electrolyte solution to a glow discharge space. The device also includes a counter electrode in the form of a second hollow capillary that can deliver the analyte into the glow discharge space. A voltage across the electrolyte solution and the counter electrode creates the microplasma within the glow discharge space that interacts with the analyte to move it to a higher energy state (vaporization, excitation, and/or ionization of the analyte).
    Type: Grant

    Date of Patent: April 23, 2019
    Assignees: Clemson University Research Foundation, Battelle Memorial Institute on behalf of Pacific Northwest National Laboratory, The Regents of the University of California—Lawrence Berkeley National Laboratory
    Inventors: R. Kenneth Marcus, Charles Derrick Quarles, Jr., Richard E. Russo, David W. Koppenaal, Charles J. Barinaga, Anthony J. Carado
