An overview is given about the new developments in GDMS, both with respect
to the glow discharge source as to the coupling with various kinds of mass
spectrometers. Moreover, as for every analytical technique, methodological
and fundamental research is being carried out to improve the analytical res
ults of GDMS, and some of the new developments in these fields will be disc
ussed as well. Finally, the various analytical applications of GDMS will be
presented.
