| Abstract: | A technique for the determination of the impurity composition of soluble germanium dioxide and one containing up to 0.1% insoluble in 12 M HCl 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. %. |
