| Outline of Final Research Achievements |
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).
