Basics of Electrochemical Impedance Spectroscopy

The Basics of Electrochemical Impedance SpectroscopyGamry Instruments has taken one of their most popular Application Notes, The Basics of Electrochemical Impedance Spectroscopy, and revised it into a new easy-to-read resource for researchers, academics and professionals.

This newly designed reference guide is a primer on EIS and includes descriptions, formulas, and data presentations to get you started on building your knowledge of this useful research tool. The information will be presented in a four-part series, to help you gain knowledge as you read through the material.

Why learn about EIS?

  • It is used in a wide range of industries and applications
  • It is frequently applied to the testing and analysis of coatings, corrosion, fuel cells, batteries, solar cells, sensors and physical electrochemistry.

Part 1 and Part 2 have been recently released with easy-to-reference formulas and topics including:

  • Electrolyte Resistance
  • Double Layer Capacitance
  • Polarization Resistance
  • Charge Transfer Resistance

Part 2 discusses Physical Electrochemistry and Equivalent Circuit elements available for Download at
