Abstract

Absolute values have been obtained for the isotopic abundance ratios of common, equal-atom, and radiogenic lead isotopic standards using solid-sample mass spectrometry. Samples of known 208Pb/206Pb ratio, prepared from nearly pure separated 206Pb and 208Pb solutions, were used to calibrate the mass spectrometers.
