| Outline of Final Research Achievements |
Feedback-based flow ratiometry (FB-FR) is a sophisticated variation of flow analysis, first reported by Tanaka et al. in 2000. Flow ratio of sample and reagent solutions is continuously varied by variable and subsequent fixed triangular waves. Information on analyte is obtained by analyzing the relationship between sample/reagent flow ratio and detector output signal. Throughput rate can be increased by a feedback-based control.
In this study, air segmentation approach has been introduced to a flow titrimetry by FB-FR. Axial dispersion was limited in each liquid segment separated by air bubbles, resulting in the expansion of applicable range. The FB-FR system with unprecedented high throughput rate (max. 50 titrations/min, in non segmented mode) was also developed. FB-FR was further applied to a process control, where online analysis and control were carried out by coupling two kinds of feedback-based controls.
