Multielement Analysis of Rocks with the Use of Geological Certified Reference Material by Inductively Coupled Plasma Mass Spectrometry

抄録

A multielement analysis in rocks, based on inductively coupled plasma mass spectrometry, is described. Major interferences observed were the background signals for P, K, Mn, Fe and the doubly charged and oxide ions for Ni, Cu, Zn, Ga, Eu, Tb, Yb, Lu. Both geological certified reference material JB-1 as standard and indium internal standard were used to correct the matrix effect; 49 major and minor elements in rocks were determined successfully by using this method.
