Glow discharge mass spectrometry (GDMS) is the state-of-the-art analytical technique
for the bulk elemental analysis of inorganic solid samples. Glow discharge mass
spectrometry is the most comprehensive and sensitive technique available for the
analysis of solids. It is capable of analyzing, conducting, semi-conducting and
insulating samples. It is amenable to solids, powders, crystals, wafers, and many
other sample forms. Its elemental coverage encompasses lithium through uranium with
the ability to determine impurity levels from the sub-ppb range to the percent level.
The advantages of glow discharge mass spectrometry include total elemental coverage,
high precision, low detection limits, quantitative accuracy (+25% on average),
without the use of standards. High resolution capabilities eliminate most spectral
interferences.
