Evaluation of Error Propagation in Lead Isotope Analysis of Ancient Melt Inclusions by LA-MC-ICP-MS

Yankuang ceshi, 2015
Determination of Pb isotopes in melt inclusions by Laser Ablation -Multiple Collector-Inductively Coupled Plasma-Mass Spectrometry (LA-MC-ICP-MS) is limited to samples formed later than Mesozoic because U and Th signals are not monitored.

Precise and accurate isotopic analysis of microscopic uranium-oxide grains using LA-MC-ICP-MS [PDF]

Journal of Analytical Atomic Spectrometry, 2009
Uranium isotope (235U, 236U, 238U) ratios were determined for microscopic uranium-oxide grains using laser-ablation multi-collector inductively-coupled-plasma mass-spectrometry (LA-MC-ICP-MS). The grains were retrieved from contaminated soil and dust samples.

In Situ Ti Isotopic Measurements by Laser Ablation MC-ICP-MS

Terrestrial, Atmospheric and Oceanic Sciences, 2009
We have been developing Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS) technique to measure titanium isotopic composition in situ. A principal aim of this work is to search for isotopic heterogeneities larger than

In situ boron isotope measurements of natural geological materials by LA-MC-ICP-MS

Chinese Science Bulletin, 2010
There are two main methods to determine boron isotopic composition. One is the solution method, in which boron is purified after the samples are dissolved in solution and the boron isotope ratios are determined by thermal ionization mass spectrometry (P-TIMS and N-TIMS) or multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS).

In situ lithium and boron isotope determinations in mica, pyroxene, and serpentine by LA-MC-ICP-MS [PDF]

Chemical Geology, 2015
Boron and Li are light, incompatible elements that preferentially partition into the liquid phase, whether melt or aqueous fluid, and thus are useful for tracking fluid-related processes in rocks. Most of the Li isotopic data presently available on subduction-related rocks are from whole-rock analyses; and the B isotopic analyses of subduction material
