采用Activa-M分析地质样品

This application note describes the analysis of several elements(Ba, Be, Co, Cr, Cu, Nb, Ni, Rb, Sc, Sr, V, Y, Zn and Zr) in geological samples, with the ACTIVA-M ICP-AES
instrument. Analysis of geological samples requires an
ICP-AES instrument with good resolution and robustness,
to compensate for the variability of matrix and the influence of the major elements.
The material was dissolved by fusion with LiBO2 in a
Pt9u5 crucible. The calibration was performed with 3
different certified reference materials (GSR-1 (Granite),
GSR-2 (Andesite) and GSR-3 (Basalt)) from IGGE, China.
A Kimberlite sample (SARM 39) was then analyzed to validation the analytical methodology. For the determination
of low concentrations of Rb, a specific optimization was
realized and is detailed. 高性能ICP光谱仪
