高時間分解能多重検出器型ICP質量分析計による隕石ナノ粒子の個別同位体分析
Isotopic analyses of Pt and Ir from chondrite matrix were conducted by a multiple collector-ICP-mass spectrometry equipped with high-time resolution ion counters. To obtain reliable data, correction of counting loss due to detector dead time is highly desired. We have developed new correction method for the dead time. With the technique developed here, Pt and Ir isotopic data can be derived from individual nanoparticles from chondrite matrix. Isotopic signature obtained here will be discussed.
