How to reduce noise in OCP and EIS study using Potentiostat?

16 November 2022 0 9K Report

Dear all,

I have been doing trials for accessing corrosion properties of steel rebar in chloride environment using Potentiostat, wherein my working electrode is steel rebar, reference electrode is Ag/AgCl and counter electrode in titanium mesh.

From initial trials, I encountered several problems listed below:

1. My OCP is not properly getting stabilized

2. My EIS analysis shows noisy data at high frequency and no proper pattern

What can be the reason behind such observations and how to correct them?
