What is the Equivalent Circuit Model for Capillary or Microchip Electrophoresis Electrodes?

09 April 2020 0 186 Report

Hello,

Is there anyone who measured and modelled or determined equivalent circuit model for capillary (microchip) electrophoresis electrodes using electrochemical impedance spectroscopy?

Could you, please, provide references?

Thanks
