安定同位体およびキラリティーを利用した絶対定量法は，比較標準を必要とせず，試料からの目的成分の定量的な回収も必要なく，精確な定量が可能である。生物環境試料中の超微量の無機および有機化学種に対し，新規な分離法と計測法に基づく絶対定量法の開発を目指し，主に１）ミクロシスチンの酸化分解化合物3-メトキシ-2-メチル-4-フェニル酪酸のキラルキャピラリー電気泳動分析，２）水溶性ポルフィリンの液液界面吸着化学種の偏光変調全内部反射蛍光分光法の開発，３）アミノ酸類の不足当量同位体希釈NMR分析法の開発，４）同位体交換反応を用いる微量銅(I,II)化学種の同位体希釈質量分析などの成果を得た。
Absolute determination methods based on the isotope dilution principle using radio or stable isotopes or enantiomeric isomers are accurate and precise analytical methods in which any comparison standards and the quantitative recovery of the chemical species in question are not necessary. In this study, the following works are pursued. 1) capillary electrophoresis for the enantiomeric isomer dilution of 3-methoxy-2-methyl-4-phenylbutyric acid which is the common product derived from microcystins, 2) development of the polarization-modulation total internal reflection fluorescenc spectroscopy (PM-TIRF) for adsorbed species of water-soluble porphyrins at liquid/liquid interfaces, 3) development of the substoichiometric isotope dilution NMR analysis for trace amino acids, 4) fundamental study of the species-selective isotope dilution analysis of copper(I,II).
