| Research Abstract |
Amplitude modulated multiplexed flow analysis is a new concept for simultaneous analysis of multiple samples based on frequency analysis. In this study, we have 1) improved the throughput of the measurement by the optimization of the system and analytical conditions, 2) proposed a concept for the simultaneous determination of multiple analytes in a sample, and 3) limited the axial dispersion through the segmentation of the liquid stream with of air-bubbles for sensitivity enhancement. The developed system has successfully been applied to the determinations of phosphate ions, chloride ions, ferrous & ferric ions, nitrite & nitrate ions, and so on, in environmental water samples.
