We present diagnostics of plasma pencil discharge as alternative excitation source for analytical chemistry. The plasma pencil is special type of rf plasma nozzle at atmospheric pressure. Through this nozzle flows working gas argon with aerosol. The aerosol sample introduction system employed a double pass Scott spray chamber with a pneumatic concentric nebulizer. The parameters of the plasma were calculated by optical emission spectroscopy.<br /><br />

The results of a comparative study of the relative analytical performance of different nebulizer and spray-chamber designs with a direct-current plasma (DCP) are described. Concentric-glass, cross-flow, and Babington-type nebulizers were each evaluated with either a double-pass or an open spray-chamber geometry for the effect of each combination on the observed linear dynamic range and the magnitude of interferences arising from the presence of an easily ionizable element (sodium) and difficult-to-vaporize species (phosphate salts). The performance of each of these combinations was compared to that of the nebulizer/spray-chamber configuration provided by the manufacturer. For nearly all cases, the manufacturer's configuration provided, at worst, comparable signal intensities for all conditions investigated.
