Abstract
A nonradioactive atmospheric pressure method for ionization of analytes comprises creating an electrical discharge in a carrier gas thus creating metastable neutral excited-state species. The carrier gas containing the excited-state species is directed into a reactant gas to form ions of the reactant gas. The ionized reactant gas is then directed at the analytes at atmospheric pressure near ground potential to form analyte ions.
