| Abstrakt: | 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 208 Pb/ 206 Pb ratio, prepared from nearly pure separated 206 Pb and 208 Pb solutions, were used to calibrate the mass spectrometers. |
