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.

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 ...

Emerging applications of high-precision Cu isotopic analysis by MC-ICP-MS

Science of The Total Environment, 2022
As a component of many minerals and an essential trace element in most aerobic organisms, the transition metal element Cu is important for studying reduction-oxidation (redox) interactions and metal cycling in the total environment (lithosphere, atmosphere, biosphere, hydrosphere, and anthroposphere). The "fractionation" or relative partitioning of the

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.

Effective Correction of Mass Bias for Rhenium Measurements by MC‐ICP‐MS

Geostandards and Geoanalytical Research, 2009
The geochemistry of Re‐Os and the recent use of Re as a non‐traditional stable isotope both need accurate and precise quantification of 187Re/185Re ratios. This paper reports rhenium isotopic data obtained from the analysis of a standard solution and geological samples by MC‐ICP‐MS.
