Electrochemical Impedance spectroscopy
|
Electrochemical Impedance Spectroscopy (EIS) is a powerful non-destructive technique for characterizing layered structures and surfaces, interfacial phenomena, solar cell materials, fuel cells and much more.
Typically the impedance results are modeled as a combination of electrical resistors and capacitors so that, in well defined samples, the thickness and electrical properties of the constituent sub-layers can be determined. The results are generally complementary, and cost effective, when compared to other surface analysis methods such as electron or atomic force microscopy, neutron reflectometry, or quartz crystal microbalance gravimetry.
Typical application areas are varied and include surface corrosion, membrane structure and permeability, self-assembled monolayers (SAMs), biosensors, epitaxial layers, interfacial ion transport, battery and fuel cell characterization and performance, and biocompatible surfaces.

eDAQ ERZ100
Our product range include the eDAQ ERZ100 system, which is an economical solution for routine or teaching EIS experiments, where extreme resolution and accuracy is not required. It works with the eDAQ ET163 Potentiostat up to 100kHz, or any existing potentiostat that can accept an external signal and provide analog current and potential signals.
INPHAZE EIS
If extreme accuracy and resolution is required, the INPHAZE system provides industry-leading performance and the best accuracy and resolution on the market. The INPHAZE EIS is capable of accurately characterizing multilayer structures and biological structures down to monolayer thickness.
