I am building a potentiostat using very common circuit design. After completion, how do I validate if this potentiostat is accurate? I am mostly only interested in EIS measurement.
What is the golden standard to validate if a self-made potentiostat is accurate or not, especially in EIS measurement accuracy? I know you can use CV of known redox couple to validate the potentiostat, but can that result translated to EIS accuracy? Any important experiments in wet lab to verify EIS?
Generate a simple Randles circuit using resistors and capacitors of known values. Short the reference and counter electrode and attach to one terminal of the circuit. Attach the working electrode to the other terminal.
Dear Sir, you would need to perform accuracy contour plots using high precision electrical components...

Build a simple RC circuit with resistor and capacitor, calculate the transfer function, and compare it on your potentiostat measurement.
