Abstract

マルチコレクターを有するICP質量分析法(MC-ICP-MS)を用いた同位体分析法を紹介する.本報告では,高精度同位体分析において問題となる同位体質量差別効果とその補正法について述べる.幾つかの元素の同位体組成を系統的に測定することにより,MC-ICP-MSに見られる同位体差別効果補正係数が,分析元素の質量数に対して正の相関をもつことが分かった.又,この特性を利用した新しい外部補正法を開発し,得られるデータの確度(TIMSからのずれ)を向上することができた.

This paper describes advances in isotopic measurements that have been made with an inductively coupled plasma source magnetic sector multiple collector mass spectrometer (MC-ICP-MS) and presents results of new experiments aimed at further evaluating the instrumental capability as well as the correction technique for the mass discrimination effects. The ability to correct for the mass discrimination effect using a second element of similar mass and very high sensitivity for elements that are otherwise difficult to ionize gives this instrument major advantages over other conventional techniques for isotopic measurements.<BR>The isotopic data obtained by MC-ICP-MS clearly demonstrate potential as a new technique to produce precise and reproducible isotopic data for the elements that are difficult to measure by thermal ionization mass spectrometry (TIMS).
