N2 - We have measured the contamination in an Al2O3 rod and the elemental composition in cinnabar (Tenjinyama ancient tomb) by using the electron cyclotron resonance ion source (ECRIS) and the RIKEN linear accelerator (RILAC) complex. Elements of mass smaller than 100, such as 50V, 55Mn and 75As, were mainly searched for using this system. The ionization chamber and the Si detector were used for atomic number assignment. The production of positive ions in the ECRIS is not influenced by ionization selectivity. In the measurement of elements, spectroscopic interference with molecules does not exist due to complete ionization in the resonance zone of high temperature by the ECR plasma. The development and establishment of these systems will play an important role in trace element analysis. We developed this system for practical use and also considered other possibilities for these devices.
