EIS - electrochemical impedance spectroscopy / Impedanzspektroskopie

Listing Description

The EIS is a non-destruktive analysis method to characterize the response of a system to the applied ripple current capabilites. Each system as well as each process can be described and modelled with a combination of resistances, capacities and inductivities. EIS allows a survey of condition of solid materials as well as the analysis of processes like Korrosion, passivation, fuel cells, batteries). With the modelled equivalent circuit, for example a corrosion process can be described and the corrosion resistance can therefore directly be taken from the measurement values.

Offer Details

Specifications and Deliverables:

The measurement values can be visualized in a Bode-Diagramm showing the Phase in degrees and the impedance in ohm. The characteristics of the curve contain information about the descrete elementes of the system such as the resistance of the electrolyte, the resistance of the pores as well as about corrosion processes and the beviour of the coatings within the liquid electrolyte.

Value Proposition:

By using the EIS a better understanding of the electrochemical system ist possible. For example you can judge if a newly developed coating is dense and free of pores, so that a long term corrosion protection might be realized. Moreover one can also detect the porosity of the coatings and measure the resistance. In so doing one can meaure the conductivity of the system.
