Mass discrimination in the measurement of lead isotope reference samples (original) (raw)

Abstract

This paper presents a study of the adjustment of published values for lead isotope reference materials by the double spike technique. The objective was to learn, through hindsight, about the characteristics of common analytical errors in lead isotope analyses. The conclusion is that the great majority of such errors are substantially reduced by the double spike technique. The results emphasize the precision with which the isotope ratios of the Broken Hill and California Institute of Technology reference materials are known.
