Determination of Impurities in High-Purity Germanium Dioxide Using Atomic Emission Spectrometry

摘要

A technique for the determination of the impurity composition of soluble germanium dioxide and one containing up to 0.1% insoluble in 12 M HC1 is described. The technique offers the possibility to control the content of 31 impurities simultaneously after preconcentration with detection limits of about 10~(6)to 10~(-8) wt% and with an intralaboratory precision not exceeding 20 rel. %.
