To be considered reliable, EIS measurements must be performed on a system that is linear, in a steady-state and time-invariant. Quality Indicators are made available to users of EC-Lab® to ensure that the system fulfills these requirements.
When Electrochemical Impedance Spectroscopy (EIS) should be performed under potentio control (PEIS), galvano control (GEIS) and when GEIS-AA should be used.
The effects of corrosion need to be considered in almost every industry. A recent NACE report [1] estimated that corrosion costs $2.5 trillion USD globally
Electrochemical impedance spectroscopy (EIS) is a powerful analytical method used to investigate the electrochemical properties of a wide range of electrochemical systems
