Lead isotope ratio measurements in geological glasses by laser ablation-sector field-ICP mass spectrometry (LA-SF-ICPMS)

In this paper, we present the first LA-SF-ICPMS Pb isotope data for the MPI-DING (KL2-G, ATHO-G) and USGS reference glasses (BCR-2G, BHVO-2G) which may be useful for microanalytical in situ Pb isotope analysis. The findings of small (<2%), but significant differences in Pb isotope ratios of Hawaiian glasses of different ages, demonstrate that LA-SF-ICPMS is a suitable tool for geochemical research.
