| Outline of Final Research Achievements |
We developed simple and sensitive reversed phase liquid chromatographic methods for the analyses of hydrophilic compounds (HCs) using on-line complexation with metal ions. When metal ions are added to the mobile phase, they coordinate with HCs and therefore may influence the retention of HCs. Moreover, the absorption bands of HCs may shift to longer wavelengths and their extinction coefficients may increase. In this study, we developed reversed-phase liquid chromatographic methods with UV detection to determine organic acids as their copper complexes and alditols as their molibdate complexes. The developed methods were used for quantitative determination of organic acids and alditols in food samples.
