Hi @PJS

Im using a glassy carbon working electrode, Ag/AgCl reference electrodes, and a graphite as a auxiliar electrode. For preconcentration i use ConstantVoltage (-400mV, 45 sec) and for stripping i use LSV -(start:-1000mV, Stop:-100mV , slope:20 mV/sec). I'm trying to determinate lead between 10 ppm and 50 ppm. I would really appreciate it if you could show your results with the parameters you use.

Hi @Jo
Thanks for sharing the experiments with the RodeoStat, I think it is a very good alternative, however I try to do something similar to what is proposed there. I am currently doing IoT based on the CheapStat, I had difficulties in the electrochemical sensing part.

I am trying to determine the lead in the water using the stripping voltammetry (constant voltage mode for the preconcentration + LSV for extraction), but I can not get good results, could someone perform similar tests with success or some reference of a journal using cheapstat for heavy metal detection? thanks
