摘要:Abstract(#br)Two new macro-sublimation methods allowing processing of larger sample volumes with lower concentration requirements in solution are developed and systematically assessed. Development of these methods involved the design of two new pieces of lab apparatus; 15-mL...

摘要:Abstract(#br)Multiple-collector inductively coupled plasma mass spectrometric (MC-ICPMS) techniques, with high-precision and high-throughput capabilities, have been applied to 230 Th/U geochronology since the late 1990s. Significant effort has been dedicated to refining such t...

摘要:... The isotope composition of Te is then determined by multiple-collector inductively coupled plasma-mass spectrometry (MC-ICPMS). Tellurium has a very high first ionization potential and thus MC-ICPMS is much more suitable for the isotopic analyses than positive ion thermal ...

摘要:... Here, we report Zr stable isotopic data for terrestrial igneous rocks and present a novel method for the determination of Zr stable isotope ratios within natural geological materials using ion exchange, double-spike, multiple-collector inductively coupled mass spectrometry (MC-ICPMS...

摘要:Abstract(#br)We demonstrate the utility of uranium-series age dating using laser ablation multi-collector inductively coupled plasma mass spectrometry (LA MC-ICPMS) to ‘range find’ a large suite of fossil corals in order to select those for subsequent detailed and high res...

摘要:... The latest generation of multicollector inductively coupled plasma mass spectrometry (MC-ICPMS) instrumentation offers the capability of using Pb isotopic signatures as a tool for environmental source tracking in public health. We present a case where MC-ICPMS was applied to...

摘要:... Analytical developments for measuring 234 U/ 238 U have progressed from direct alpha-counting, with precisions at the percent level, to thermal ionization and multiple-collector inductively coupled plasma mass spectrometry (TIMS and MC-ICPMS, respectively) isotopic measu...

摘要:Abstract(#br)Techniques for the purification of Si for the determination of its natural stable isotopic composition have in the past been based on the requirements for gas-source mass-spectrometry, rather than MC-ICPMS. For high precision analyses by MC-ICPMS it is essential to ...

摘要:Abstract(#br)This work presents a rigorous assessment of the accuracy and precision with which 176 Hf/ 177 Hf can be measured in rutile by laser ablation (LA) MC-ICPMS. For rutile with ≥ 40 ppm Hf, we demonstrate that 176 Hf/ 177 Hf can be measured accurately and reproducibly ...

摘要:... MC-ICPMS provides a means to make high precision measurements but a recent laboratory inter-comparison, Regular European Inter-laboratory Measurement Evaluation Programme (REIMEP)-18, indicates that accurate results for U isotope ratios are not currently achieved by all fa...
