Activa-M地質樣品測試案例

      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 Pt95Au5 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.
