Here is presented a setup made of a combination of an injection valve, a hand‐made chromatographic microcolumn and an electrochemical detector for the simultaneous separation of Hg²⁺ and Ag⁺ ions in water. The microcolumns were packed with exchanger resin and used for the separation of Hg²⁺ and Ag⁺ ions, whereas a screen‐printed carbon electrode (SPCE) was the amperometric detector. The performances of the SPCE towards ions were firstly studied in a FIA setup. The efficiency of ion separation was then evaluated. The reproducibility, stability, and the regeneration of the obtained microcolumns were also studied and discussed.

同时分离和电化学测定水中Hg2 +和Ag +离子的微流控装置

这里介绍的装置由注入阀，手工色谱微柱和电化学检测器组合而成，用于同时分离水中的Hg ²⁺和Ag ⁺离子。微柱中装有交换树脂，用于分离Hg ²⁺和Ag ⁺离子，而丝网印刷碳电极（SPCE）是安培检测器。首先在FIA装置中研究SPCE对离子的性能。然后评估离子分离的效率。还对获得的微柱的重现性，稳定性和再生性进行了研究和讨论。
