Noise in electrochemical corrosion measurements is common, showing up in both the current and voltage signals. It originates from several different sources, including: Electronic and thermal noise in the instrument… read more →
This overview describes data-treatment for Electrochemical Noise measurements in the ZRA-control mode. Data-treatment for ECN measurements in potentiostatic or galvanostatic modes do not require a separate discussion. Those modes are… read more →
The Electrochemical Noise software uses a very simple method to measure noise. Periodically, short blocks of data are acquired using the potentiostat’s internal A/D converter. Current is measured for potentiostatic… read more →
