Z100™ Electrochemical Impedance analyzer
Description
Electrochemical Impedance Spectroscopy (EIS) has emerged as a powerful technique for
defining reaction mechanisms and physical structures involved in a wide variety of applications
including
•
•
•
•
Corrosion processes
Battery and fuel cell
Biological systems
Surface structures
The EDAQ Z100™ EIS System provides the means to turn an existing potentiostat/galvanostat
or electronic load into a fully functioning EIS System with full analysis capability.
The single channel Z100 is based on the experience gained from the development of a 6 channel
EIS system and includes many useful enhancements.
The EDAQ Z100™ EIS system covers the frequency range of mHz to 100kHz and the ZMAN
software provided with the system generates all required analysis outputs.
The complete system is software controlled and all functions such as ranging, calibration, and
measurements can be automated.
