Lead Isotopic Compositions of Environmental Certified Reference Materials for an Inter-Laboratory Comparison of Lead Isotope Analysis

Lead isotopic compositions of environmental certified reference materials for an inter-laboratory comparison of lead isotope analysis.

Lead isotope ratios, viz. 207Pb/206Pb and 208Pb/206Pb, of the commercially available certified reference materials (CRMs) issued in Japan are presented with an objective to provide a data set, which will be useful for the quality assurance of analytical procedures, instrumental performance and method validation of the laboratories involved in environmental lead isotope ratio analysis. The analy...

Iron Isotopic Compositions of Geological Reference Materials and Chondrites

High-precision iron isotopic compositions for Fe-bearing geological reference materials and chondrites with a wide range of matrices (e.g., silicates, oxides, organic-bearing materials) are reported. This comprehensive data set should serve as a reference for iron isotopic studies across a range of geological and biological disciplines for both quality assurance and inter-laboratory calibration...

Evaluation of Methods for Analysis of Lead in Air Particulates: An Intra-Laboratory and Inter-Laboratory Comparison A manuscript submitted to Environmental Science: Processes and Impacts

Lead and zinc dust depositions from ore trains characterised using lead isotopic compositions.

This study investigates an unusual source of environmental lead contamination - the emission and deposition of lead and zinc concentrates along train lines into and out of Australia's oldest silver-lead-zinc mine at Broken Hill, Australia. Transport of lead and zinc ore concentrates from the Broken Hill mines has occurred for more than 125 years, during which time the majority was moved in unco...

Study of normalization method of isotopic compositions to isotope reference scales

In stable isotope ratio mass spectrometry (IRMS), the stable isotopic composition of samples is measured relative to the isotopic composition of a working gas. This measured isotopic composition must be converted and reported on the respective international stable isotope reference scale for the accurate interlaboratory comparison of results. This data conversion procedure, commonly called norm...
