N2 - Polyatomic ions often formed in an ionization source during mass spectrometric analysis. The presence of such ions can complicate the analysis of high-purity substances because they interfere with analyte determination at the ng g-1 level. Collision cell technology in inductively coupled plasma quadrupole mass spectrometry (CCT-ICP-QMS) in kinetic energy discrimination (KED) mode is commonly used to eliminate polyatomic interference. Herein, high-purity germanium and germanium dioxide were examined alongside the effects of the Ge matrix. The dependence of the ratio of the analytical signals to the background signal and limits of detection (LODs) of the analytes with varied CCT-ICP-QMS instrumental parameters (helium flow rate and cell voltage) was established. It was possible to alleviate polyatomic interferences from35Cl16О+,40Ar16OH+,38Ar18OH+,70GeH+,40Ar35Cl+,73Ge16O+,74Ge16O+ on51V+,57Fe+,71Ga+,75As+,89Y+ and90Zr+, respectively. The listed analytes LODs ranged from 0.05 to 1 μg g-1 and those of Ni, Sc, and Sr were reduced by an order of magnitude compared with the determinations by ICP-QMS in standard mode. The CCT-ICP-QMS method was validated using spike experiments and the results of CCT-ICP-QMS and direct current arc optical emission spectrometry (DCA-OES) analyses were compared.
