Quantitative Ion Probe Analysis Of Glasses By Empirical Calibration Methods.

The range of applicability of the empirical sensitivity factor approach in ion probe analysis of glasses was investigated. Accurate results were achieved only when the standards and sample contained the same major element (excluding oxygen) in the glass matrix. With the above criterion satisfied, modification of the basic external standard approach was not necessary since other interelement matrix effects were minimal. Analyses in the range of error factors of 1.15 were obtained using average relative sensitivity factors.
