Here we present an analytical method for Cu isotopic measurement using standard-sample bracketing on a Nu Sapphire multi-collector inductively coupled plasma mass spectrometer. The effects of Cu concentration and HNO3...

Two clinopyroxene megacrysts, DMP-2 and DMP-3, were collected from Cenozoic alkali basalts in the Hannuoba region of China. They were characterised for major and trace element compositions for in situ microanalysis. EPMA and LA-ICP-MS analyses indicate homogeneity in the element mass fractions in both clinopyroxene samples. Bulk analyses using various techniques (XRF, ICP-OES and solution ICP-MS) also reveal good consistency in their major and trace element data. They, thus, can be used as potential reference materials for elemental in situ microanalysis. Accordingly, element mass fractions are recommended for thirty-two elements.

Here we present a high-precision analytical method for lithium (Li) isotopic analysis using standard-sample bracketing on a Nu Sapphire collision cell multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS). A modified...
