Whole rock multiple trace element analyses using fused glass bead by laser ablation-ICP-MS

Abstract

(2016) Whole rock multiple trace element analyses using fused glass bead by laser ablation-ICP-MS. Abstract: A simple analytical method for whole rock trace elements covering a mass range of 45 Sc-238 U using laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) with a high-dilution ratio (sample:flux = 1:10) glass bead for X-ray fluorescence spectrometry (XRF) has been established. The reproducibility (shown as relative standard deviation of signal intensities) of analytical results of the Geological Survey of Japan (GSJ) geochemical reference materials was mostly < 30%, except for elements of very low contents. A comparison with the compilation values from literature values and the analytical results of this study show < 30% difference (DIF) for 194 out of 225 elements analyzed from JB-2, JA-1, JR-1, JGb-1 and JG-1a. Results of > 30% DIF were elements of very low contents in most cases. Analytical results of JB-1b obtained in this study were concordant with the literature values. The quantitative values obtained in this study can be used for petrological and geochemical discussions of whole rock trace elements.
