Tin isotopes via fs-LA-MC-ICP-MS analysis record complex fluid evolution in single cassiterite crystals

American Mineralogist, 2021
Tin isotope geochemistry of cassiterite may allow for reconstructing the fluid evolution of tin ore deposits. Here, we present cathodoluminescence (CL) imaging, trace element, and in situ Sn isotope compositions of two cassiterite crystals from an early ...

Vanadium isotope measurement by MC-ICP-MS

Chemical Geology, 2016
Abstract We present a method to measure vanadium (V) isotopic composition for terrestrial rocks in this study. Vanadium was efficiently separated from matrix elements by a chromatographic technique using cation- and anion-exchange resin columns, avoiding the expensive TRU Spec resin.

Sulfur-induced offsets in MC-ICP-MS silicon-isotope measurements

Journal of Analytical Atomic Spectrometry, 2009
Sample preparation methods for MC-ICP-MS silicon-isotope measurements often involve a cation-exchange purification step. A previous study has argued that this would suffice for geological materials, as the occasional enrichment of anionic species would not compromise silicon-isotope analysis.

Precise Analysis of Gallium Isotopic Composition by MC-ICP-MS

Analytical Chemistry, 2016
Though an isotope approach could be beneficial for better understanding the biogeochemical cycle of gallium (Ga), an analogue of the monoisotopic element aluminum (Al), the geochemistry of Ga isotopes has not been widely elaborated. We developed a two-step method for purifying Ga from geological (biological) samples for precise measurement of Ga ...

An optimal separation method for high-precision K isotope analysis by using MC-ICP-MS with a dummy bucket

, 2020
Previous studies have shown that significant K isotope fractionation is found in continental weathering, oceanic crust subduction, and plant growth, suggesting that K isotopes could be a potentially important tracer.

Isobaric Spike Method for Absolute Isotopic Ratio Determination by MC-ICP-MS

Analytical Chemistry, 2020
Absolute isotopic ratios are required for isobaric interference corrections, spike calibrations, and isotopic analysis by external normalization methods. However, high-precision natural isotopic abundance data are lacking for many elements, particularly those with less than four isotopes or having isobaric isotopes with other elements.
