Potentiostat wave-like waveform output of the system on square wave voltametry

This is a question I managed to solve! But because it took me 2 weeks to find out the issue and write this whole question, I leave it here for anyone that might face the same issue at the future. Short question: I use this hookup as part of a…

Potentiostat circuit: Cannot understand how op-amp behaves

I am replicating this potentiostat schematic. It eventually works as I want it to, and I get the desired readings on the output. I input a voltage in the Vin (top left), and I get the Vout at the right. I do not use the "Output reference" at the…

Electrochemical Gas Sensor Potentiostat Circuit

I guess this is more of a review request than a specific question, but I was wondering if anyone has any experience with electrochemical sensors and the required circuits for gaining accurate measurements from them. Even if it's not specific to this…

Potentiostat calibration and measurement

Maybe this question is obvious, but I'll try. I am trying replicate this potentiostat without R5: In the interests of calibrating it I've joined the reference and the counter electrode to resistor of 10k ohm in the other extreme of the resistor…

Is the potentiostat resistor wrong in this PDF?

I was reading this potentiostat paper: (which was found here) I was wondering how this I/V current to voltage converter works to the right. Correct me if I am wrong here. I am pretty sure it goes like this: Iwe flows in or out from the virtual GND…

Why does output voltage drop when charging battery?

I'm an electrochemical engineer. I saw a video showing although the output voltage from transformer is about 16.5V without connection, the voltage immediately drops to 9.86V, slightly higher than the open circuit voltage of a battery to be…
