Impurity Analysis | GDMS (Glow Discharge Mass Spectrometry)

GDMS is a method suitable for evaluating trace impurities (ppm-ppb wt) and can simultaneously measure almost all elements except for gas components with stable isotopes.

GDMS (Glow Discharge Mass Spectrometry) is a method suitable for the evaluation of trace impurities (ppm-ppb wt) and can simultaneously measure almost all elements with stable isotopes on the periodic table, excluding gas components (*). Samples with conductivity are preferred, but EAG Laboratories possesses technology that can stably measure not only conductive samples but also semiconductors and insulators, allowing for impurity analysis in oxides, nitrides, and carbides.
