GLOW DISCHARGE MASS SPECTROMETRY (GDMS)
The state-of-the-art analytical technique for
the bulk elemental analysis of inorganic solid samples. GDMS 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. GDMS
advantages include total elemental coverage, high precision, low detection limits, quantitative
accuracy (+25% on average), without the use of standards and its high resolution capabilities
eliminate most spectral interferences.
