Development and Characterization of a 9-mm Inductively Coupled Argon Plasma (ICP) Source for Atomic Emission Spectrometry.

Abstract

A new 9-mm (i.d.) inductively coupled plasma torch is described which supports a stable, analytically useful plasma at less than 500 watts of r.f. power and 7 L/min total argon gas flow. Detection limits, working curves and other analytical characteristics of the new device are compared with those of both a miniature (13-mm i.d.) and conventional (19-mm i.d.) ICP. Although temperatures of the new plasma are somewhat lower than those in the larger plasmas, the new system offers promise for future, miniaturized ICP instruments. (Author)
