Effective Correction of Mass Bias for Rhenium Measurements by MC‐ICP‐MS
Geostandards and Geoanalytical Research, 2009The 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.

Isobaric Spike Method for Absolute Isotopic Ratio Determination by MC-ICP-MS
Analytical Chemistry, 2020Absolute 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.

Isotope ratios on transient signals with GC–MC–ICP-MS
International Journal of Mass Spectrometry, 2005Abstract ICP-MS instruments with multiple ion collectors (MC–ICP-MS) provide highly precise and accurate isotope ratio measurements. These instruments are easily coupled to chromatography, laser ablation or flow injection devices because of the ICP source, and thus attract general analytical interest for measurement of highly precise element isotope ...

A validated analytical procedure for boron isotope analysis in plants by MC-ICP-MS
Talanta, 2019Boron (B) is an essential micronutrient for plant growth. Lack of valid methods for pretreatment and measurement of δ11B in plant restrict applications of it in the biosphere. Dry ashing, one step cation exchange and micro-sublimation were combined to separate and purify boron (B) in plant tissues.

Chromium isotope ratio measurements in environmental matrices by MC-ICP-MS
Journal of Analytical Atomic Spectrometry, 2016A single column separation and concentration/isotope ratio measurement method for Cr by ICP-MS (single and multicollector) was evaluated and optimized for geological and biological matrices. Results showδ53Cr homogeneity in different urban soil profiles and suggest isotopically light signature for airborne Cr emitted by steelworks.
