  • Abstract
    An atmospheric pressure microplasma ionization source operating in ambient air and nitrogen is presented. Utilizing planar dielectric barrier discharge configuration, low power operation (< 250 mW) and long continuous operating lifetime (> 5000 hours) is demonstrated. Fitting of nitrogen rotational spectroscopy measurements indicate the microplasma operates at ambient temperature. Ion intensity and signal-to-noise data generated by the microplasma are compared to those produced from a 5 mCi,63Ni foil, a radioactive source widely used in chemical detection equipment. End of life failure mode is discussed.
