Silicon Isotope Ratios in Cais: In-situ Laser-ablation Mc-icpms Measurements and Comparisons with Magnesium Isotope Ratios
Introduction: High-precision measurements of Mg/Mg by multiple-collector inductively coupled plasma-source mass spectrometry (MC-ICPMS) have been used recently in our laboratory to constrain the thermal history of calcium aluminum-rich inclusions (CAIs) [1]. Presence of primary zoning profiles in at least some CAIs points to supersolidus and subsolidus diffusion as important factors in controll...
متن کاملErratum: Measurement of zinc stable isotope ratios in biogeochemical matrices by double-spike MC-ICPMS and determination of the isotope ratio pool available for plants from soil
Analysis of naturally occurring isotopic variations is a promising tool for investigating Zn transport and cycling in geological and biological settings. Here, we present the recently installed double-spike (DS) technique at the MAGIC laboratories at Imperial College London. The procedure improves on previous published DS methods in terms of ease of measurement and precisions obtained. The anal...
متن کاملAuthenticity and provenance studies of copper-bearing andesines using Cu isotope ratios and element analysis by fs-LA-MC-ICPMS and ns-LA-ICPMS.
Whereas colored andesine/labradorite had been thought unique to the North American continent, red andesine supposedly coming from the Democratic Republic of the Congo (DR Congo), Mongolia, and Tibet has been on the market for the last 10 years. After red Mongolian andesine was proven to be Cu-diffused by heat treatment from colorless andesine starting material, efforts were taken to distinguish...
متن کاملCalibration of isotope amount ratios by analysis of isotope mixtures.
The question as to what constitutes a fully calibrated isotope amount ratio measurement still remains a topic of active research. For years, the definitive calibration approach has been by means of synthetic mixtures of highly enriched isotopes with known chemical purity to give gravimetrically defined ratios. This article outlines the core concepts and assumptions of this method and illustrate...
متن کاملDetermination of Lead and Strontium Isotope Ratios in Wines by Inductively Coupled Plasma Mass Spectrometry
Thirteen wine assortments from Romania were investigated from the point of view of their metal content and isotopic ratios Pb/Pb and Sr/Sr. The determination was performed by ICP-QMS. The aim of this study was to detect and quantitatively determine the toxic metals in some white and red wine samples and to investigate them from the point of view of isotopic ratios Pb/Pb and Sr/Sr. Six metals wi...
