“…During all of the experiments described here, the system configuration was such that emission from the discharge plasma could be viewed readily. Although the requirements of the LCDS head negate any option of the desired end-on viewing of the plasma, 14 the collection of spectral information should be integrated easily into the source with minor modifications. Because modern spectrometers are computer controlled and employ the same automation and data acquisition systems outlined here for a future LCDS-GD source, the addition of on-line depth determinations to current commercial systems should be simple.…”

“…Recent attention has turned to the use of rf-GD-AES for the analysis of bulk nonconducting (glass and ceramic) materials directly [11][12][13][14][15]. The current study is intended to evaluate the applicability of the rf-GD-AES system with respect to the analysis of glass powders.…”

Abstract. A method is described for the elemental analysis of glass powder samples by rf-GD-AES. Glass powder samples were pressed without binder to form sample disks. A brass sample holder was designed to hold the pellet onto the source and provide a good vacuum seal. Sample preparation conditions and particle sizes are shown to influence spectral characteristics and plasma stabilization times. The discharge operating parameters were optimized based on both raw analyte signal intensity (S) and signal-to-background ratio (S/B), the latter was found more useful in terms of sample-to-sample precision and quantification. A NIST Standard Reference Material (SRM 89 Lead-Barium Glass) was used to evaluate the method. The limits of detection for trace components ranged from 1-10 pg/g for several elements, depending on the concentrations of the analytes in the SRM. Sample-tosample reproducibilities were better than 10% RSD and linear calibration curves were obtained using either the Si (I) optical emission as an internal standard or the individual analyte's S/B characteristics.

“…More recently the field of application was extended to nonconducting materials by rf powered glow discharges [3][4][5]. Unfortunately, this mode is not as easy to handle as the dc mode and developments are still in progress.…”

A new radio frequency (rf) hardware is developed for glow discharge spectroscopic methods. The resulting features and its capabilities for analytical applications are discussed. The electrical equipment developed allows to work as quickly, stably, reliably and easily as known from the direct current (dc) mode. Moreover, the rf power measurement has been improved. The hardware has been developed, optimised and tested for glow discharge optical emission spectroscopy (GDOES), but nevertheless it is possible to use it for all procedures applying glow discharge sources.
