摘要：

It has long been known that new alkali ion sources utilizing thermionic emission from alkali aluminosilicates can achieve high percentages of the desired ion by a sufficiently long "burn-in." Observations are reported here of instances where increased impurity ion emission can reoccur and lead to possible measurement errors in experimental systems lacking mass spectrometers. The ratio of impurity K+ ions to Na+ ions from a burned-in Na2O·Al2O3· 2SiO2 source was measured to be 0.55.
