| Outline of Final Research Achievements |
3D-chemical analyses of trace elements were performed on high pressure synthesized samples by applying the conventional 2D-LA-ICP-MS measurements repeatedly on the same sample area. We developed the software to construct the 3D-data field and to calculate the quantitative chemical data from the selected 3D-region. These acquired quantitative data were used to calculate the partition coefficients between melt and minerals. Thus calculated partition coefficients are generally in agreement with that acquired from conventional spot LA-ICP-MS analyses. In the present study, it was found that ablation rate depends on surface condition of the sample when we adopt conventional scanning 2D-measurements. It is expected that more precise quantitative 3D-analyses of trace elements will be achieved by developing a new laser ablation method using Galvano-optical system.
