Amperometry, Chloride and Ferrocyanide Ions, Cyclic Voltammogram, Potentiostat,


This study evaluated the performance of three types of potentiostats; EmStat, CheapStat and UTMStat. EmStat is the smallest potentiostat available in the market. CheapStat is an open-source potentiostat suitable for educational applications. In addition, UTMStat is the extension of CheapStat, which was designed to overcome few weaknesses of CheapStat such as the input controller/ switch and data storage handling of the cyclic voltammogram. The cyclic voltammetry and amperometry measurements of ions ferrocyanide ([Fe(CN)6]4−) and chloride (Cl-) were carried out for each potentiostat. EmStat potentiostat is not only able to detect but also to measure ferrocyanide and chloride ions. However, CheapStat and UTMStat are only able to detect and measure ferrocyanide ions. The experiment is unable to be conducted due to limitation of waveform selection on both devices. Nevertheless, CheapStat and UTMStat could provide a reliable measurement to realize miniaturized lab-on-chip applications as shown in this study.
