Description
Applications
The Z100 Electrochemical Impednace Analyzer is a
combination of waveform generator and frequency response
analyzer, capable of working with a suitable potentiostat,
galvanostat, or electronic load, to perform electrochemical
impedance spectromtery (EIS) experiments in the range of
1 mHz to 100 kHz.
EIS is a powerful non-destructive technique for characterizing
layered structures and surfaces, and interfacial phenomena.
Typically the impedance results are modelled 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.
Software
Both Z Navigator operating software, and ZMAN analysis/
modelling software is shipped with every Z100 system.
System Compatibility
A Windows XP, Vista or Windows 7 computer is required.
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.
The eDAQ EA163 Potentiostat is compatible, please ask about
other potentiostats and electronic loads.
