1. Glow discharge for analysis
1.1 Introduction
Atomic absorption (AA), atomic fluorescence (FA), optical emission (EO) and mass spectrometry (MS) are the various analytical methods that can take advantage of these glow discharges, as illustrated in figure 1 .
Its relative simplicity and reliability, combined with reasonable cost, have made glow discharge an attractive source of direct analysis of solid samples, particularly by optical spectrometry. This is known as glow discharge spectrometry (GDS)

While many GDMS in use have been developed by analytical R laboratories from ICPMS, SSMS, electron impact source mass spectrometers, etc., various manufacturers have marketed GDMS. These include :
Fisons/VG, which in 1983 marketed a high-resolution magnetic sector GDMS, the VG 9000 (undoubtedly the best-selling GDMS),...
