Abstract
A method that includes introducing at least one analyte into a gas plasma; generating neutral species from atoms of the analyte in the gas plasma; preferentially transporting the neutral species downstream of the gas plasma relative to any ions produced in the gas plasma; and reacting the neutral species of the analyte with at least one reagent ion downstream of the plasma resulting in ion species of the analyte, wherein the at least one reagent ion is supplied by an independent ion source.
