Abstract
Disclosed is a novel apparatus for the production of a sustained inductively coupled non-argon plasma discharge in flowing gas in a 13-25 mm (analytical size) containment tube at atmospheric pressure. The apparatus is developed for elemental analysis of injected aerosol or powdered samples, and particularly for air monitoring applications.
