One of the newest and most exciting areas of glow discharge (GD) development is the coupling of radio frequency (rf)-powered GD sources with various analytical spectrometries. In this arrangement, analyses are not limited to conductive samples. Electrical insulators such as glasses, ceramics, and geological materials - some of the most difficult samples to dissolve for solution-based methods of elemental analysis - can readily be examined. The primary, distinct advantage of rf-GD over traditional spectrochemical sources is its inherent capability for the direct solids analysis of both conductive and nonconductive samples. In this report, we review the operational principles as well as the latest developments in rf-GD techniques. Because much of the initial work in the area has focused on the fundamental exploration and instrumental development of these techniques, we have chosen to focus on applications and to present some of the most recent results obtained on commercial instrumentation for both atomic emission spectrometry (AES) and MS. 41 refs., 7 figs., 1 tab.
