Abstract In this study, the performance of a source measure unit (SMU) performing cyclic and differential pulse voltammetry analyses, in comparison to potentiostat, is investigated. SMU is a versatile and accurate tool, capable of sourcing and measuring simultaneously and is comparable to the use of a potentiostat for such measurements. Here, two surface-functionalized screen-printed carbon electrodes with two different nanocomposites were utilized to represent the electrochemical system. The results unveil that the electrochemical behaviour of SMU is qualitatively comparable to that of the potentiostat with more than 97% accuracy; for both cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Consequently, SMU is feasible for CV and DPV measurements. Graphic abstract

使用源测量单元对纳米表面修饰的丝网印刷电极进行电化学表征

摘要 在这项研究中，与恒电位仪相比，研究了执行循环和差分脉冲伏安法分析的源测量单元 (SMU) 的性能。SMU 是一种多功能且准确的工具，能够同时进行采购和测量，并且与使用恒电位仪进行此类测量相当。在这里，两个表面功能化的丝网印刷碳电极和两种不同的纳米复合材料被用来代表电化学系统。结果表明，SMU 的电化学行为在定性上与恒电位仪相当，准确度超过 97%；循环伏安法 (CV) 和微分脉冲伏安法 (DPV)。因此，SMU 对于 CV 和 DPV 测量是可行的。图形摘要
