1. A method for detection of trace constituents, the method comprising the steps of:

  • a) forming a dielectric barrier discharge by applying an alternating current voltage across a dielectric barrier material;

    b) elevating the inert gas to an excited state via the dielectric barrier discharge;

    c) mixing the excited state inert gas with trace analytes; and

    d) measuring with an electrometer matter selected from the group consisting of the analytes and their byproducts.
