The two Japanese geochemical standard samples, JA-1 (Andesite) and JB-2 (Basalt), have been analysed by the Inductively Coupled Plasma Atomocomp (MODEL 90-750) and conventional wet chemical analysis. Particularly, 23 elements from Ti to Zr were measured with the ICP Atomcomp for ten times repeatedly. Analytical data were dealt with statistically and compared with the reported values. Consequently, most elements are good agreement with the reported ones except As, Cu (JB-2), Zn (JA-1).
The results are tabulated in Tables from 1 to 3.
