Abstract

A combined method of analysis of high-purity germanium dioxide by atomic emission spectrometry with matrix preseparation and trace element preconcentration was developed. The matrix was separated in an autoclave of a MARS 5 microwave system without the contact of samples with an acid solution. The method allows the determination of the following 50 analytes with the limits of detection 10–8–10–5 wt %: Ag, Al, As, Au, B, Ba, Be, Cd, Ce, Co, Cr, Cu, Dy, Er, Eu, Fe, Ga, Gd, Hf, Hg, Ho, In, La, Li, Lu, Mg, Mn, Na, Nb, Nd, Ni, P, Pb, Pr, Re, Sb, Sc, Sm, Sn, Sr, Ta, Tb, Te, Ti, Tm, W, Y, Yb, Zn, and Zr.
