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.

Accurate measurement of neodymium isotopic composition using Neptune MC-ICP-MS
Frontiers of Chemistry in China, 2008This paper reports the measurement of the Neodymium isotopic composition by Neptune Multiple Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS) over the last two years. Although there is concomitant Cerium in the chemical separation process, this has no significant influence on the Neodymium analysis.

Precise determination of lithium isotopes in seawater using MC-ICP-MS
Microchemical Journal, 2010Abstract Li (lithium) isotope analysis using MC-ICP-MS is a very powerful tracer measurement method. This is widely used for identification of Li isotopes in many fields of study. This useful method, however, has an effect on the natural Li isotope background. This is impacted by the instrument matrix.

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.
