| Outline of Final Research Achievements |
Simultaneous laser-induced breakdown spectroscopy (LIBS) and laser-ablation ICP mass spectrometry (LA-ICPMS) measurements were attempted to develop a simple analytical method for quantitative determination of whole-rock major, trace and volatile element concentration in geological materials. The method is potentially useful for rapid but quantitative evaluation of whole-rock compositions by multi-spot analyses on pressed powder pellets or cross-sections of rocks comprised of variable mixture of hydrous silicate, carbonate and phosphate minerals. However, present study revealed that simultaneous measurements of H2O, CO2 and other elements in heterogeneous samples were difficult to perform on pressed powder pellets or cross-sections with the use of 213nm Nd:YAG laser and single channel detector. Whereas, the LIBS-ICPMS tandem system can be applied for rapid determinations of major, minor and trace element concentrations in the fused-glass beads (rock powder + lithium tetraborate).
