| Outline of Final Research Achievements |
We have developed “air segmented - amplitude modulated multiplexed flow analysis (AMMFA) with no phase separation”. In this approach, liquid stream is segmented by air bubbles in order to limit the axial dispersion within each liquid segment, and thus to improve the sensitivity. Air bubbles are not physically removed. Instead, air signals are removed by signal processing with an in-house program. The developed system has been applied to the simultaneous determination of phosphate or ammonium ion in two samples. We have also studied on AMMFA utilizing periodically varying surfactant concentration in the media, and the introduction of internal standard method to AMMFA. The combination of flow analysis and frequency analysis is a unique feature of the proposed study.
