Analysis of High-Purity Germanium Dioxide by Inductively Coupled Plasma Atomic Emission Spectrometry with Reaction Distillation of the Matrix

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 m...

Zusammenfassung: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.
