Major element analysis of natural silicates by laser ablation ICP-MS†‡
The complete chemical analysis of natural silicates has previously been accomplished only by combining laser ablation ICP-MS with electron microprobe (EMP) analysis to provide complementary information on major element constituents. Here, we present a method for laser ablation ICP-MS analysis of major elements in silicate glasses and minerals that, when applied using a 193 nm laser system coupl...

متن کاملMajor- and Trace-element Analysis of Sulfide Ores by Laser-ablation Icp–ms, Solution Icp–ms, and Xrf: New Data on International Reference Materials
International reference materials representing a diverse suite of sulfide ores and related lithologies have been analyzed for major and trace element concentrations by XRF, solution ICP–MS, and laser-ablation ICP–MS (LA–ICP–MS) after fusion of the sample to a lithium borate glass. Reference materials analyzed for this study include a wide variety of bulk compositions, including ores of Pb–Zn su...
متن کاملA comparison of techniques for measuring the trace element content of human teeth: laser ablation ICP-MS versus solution ICP-MS of micromilled enamel
Through analysis of their chemical composition, human teeth may serve as retrospective bioindicators of preand postnatal nutrition and exposures to environmental pollutants. The research presented here explores the agreement of laser ablation ICP-MS and solution ICP-MS analyses aimed at capturing temporal changes in the trace element composition of enamel. Good agreement was found for LA-ICP-MS...
متن کاملEnhancing Laser Ablation ICP-MS using Sector Field Technology
• Multi-Element Analysis Introduction Laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) has developed over recent years to become a sophisticated tool for the multielemental and isotope ratio analysis of solid samples. Besides a true multi-elemental capability, independent of matrix, the major requirements for most geological laser applications in ICP-MS are the highest se...
