Electrochemical impedance spectroscopy

  • Impedance Spectroscopie Equipment

Dielectric or impedance spectroscopy is performed with a 4192A Hewlett Packard Impedance Analyzer to study the AC response of novel superionic materials in the frequency range 5Hz – 13MHz. A Novocool cryosystem allows to follow the response between 173 and 273 K. Higher temperatures can be reached with home-built furnaces. The sample is pelletized and can be measured under inert gas atmosphere in a Novocontrol sample cell developed for liquids.
