This kind of correction is expected to cause only a minor peak separation reduction, because subtraction is a linear function of potential, but it has a better alignment with the zero-current line. This effect can be observed as a blue curve in Fig. , where the current from a parallel resistor with different resistance was subtracted. In both manual corrections, the influence of double-layer capacitance was also artificially subtracted (a 50 µF capacitor). No combination of resistors and capacitors in the manual corrections was able to reproduce the hardware correction of the potentiostat. This issue is even more important, as in the case of low scan rates, hardware correction yields larger peak separation compared to the raw data -which is not intended. Manual corrections, on the other hand, behave similarly regardless of the scan rates and regardless of whether the double-layer effects are subtracted or not.
