Study on Amplitude Modulated Multiplexed Flow Analysis and Its Improvement to Analysis of Practicality

调幅复用流分析是在频率分析的基础上提出的多样本同时分析的新概念。在本研究中，我们通过对系统和分析条件的优化，提高了测量的通量；2)提出了样品中多种分析物同时测定的概念；3)通过对液体流进行气泡分割，限制轴向色散，提高灵敏度。该系统已成功应用于环境水样中磷酸盐离子、氯离子、亚铁和铁离子、亚硝酸盐离子等的测定。

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.
