Electrochemical Impedance Spectroscopy (EIS) is now ubiquitous in the electrochemical research, development, and quality-control world.

Introduction

This Technical Note concerns electrochemical impedance spectroscopy (EIS), and assumes that you have read and understand the material covered in the Application Note “Basics of Electrochemical Impedance Spectroscopy.

IntroductionElectrochemical Impedance Spectroscopy (EIS) measurements are more often performed in potentiostatic mode than under galvanostatic mode. The reason is partly convention and partly driven by materials.

Purpose of This NoteThis Technical Note outlines how waveform signals are generated with a potentiostat.

IntroductionWith the introduction of a constant phase element (CPE) as a replacement for the capacity in EIS measurements, most of the experimentally obtained results could be fitted by commercially available…

Theory and Application of Transmission Line Models to High Surface Area ElectrodesPurpose of This NoteThis application note discusses theory and practice of transmission lines.

Accurate EISGamry Instruments prides itself on performing accurate EIS. We publish an Accuracy Contour Plot (ACP) for every instrument we sell.

This application note discusses Raman spectroscopy and its combination with electrochemical techniques. The theory of Raman spectroscopy and the effect of light on matter are explained.

IntroductionElectrochemical Impedance Spectroscopy (EIS) is a powerful way to gain information about electrochemical systems, often applied to new electrochemical devices used for energy-conversion and storage (ECS), including batteries, fuel cells,…

IntroductionWith Gamry’s Echem Analyst and Model Editor you can create all sorts of EIS models, provided they are made up of series and parallel combinations of eight different basic circuit…
