Quantitative Analysis of Zirconium Oxide by Direct Current Glow Discharge Mass Spectrometry Using a Secondary Cathode

Abstract

A dc GD mass spectrometer has been used for the analysis of ZrO₂ samples with known amounts of artificial impurities. For this purpose the secondary cathode technique has been used. The research work focused both on the methodological aspects of the atomization of the ZrO₂ and on some quantitative aspects, with direct analytical interest. The reproducibility was found to be better than 10% RSD in most cases; the accuracy of the ‘standardless’, raw results was within a factor of 2–3 of the known concentration.
