Electrochemical impedance spectroscopy (EIS) is a powerful technique that utilizes a small amplitude, alternating current (AC) signal to probe the impedance characteristics of a cell.

This application note discusses Raman spectroscopy and its combination with electrochemical techniques.

This Application Note describes measurement of very small impedances using Electrochemical Impedance Spectroscopy (EIS).

This application note describes a series of EIS measurements made on a 1mW surface-mount resistor.

With 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 8 different basic circuit components.

This application note discusses the use of multiple sine wave excitation in EIS and its implementation in Gamry Instrument software.

All my impedance spectra look the same! This complaint is very common.

Transmission lines are regularly used to model the impedance spectra of porous systems.

This application note is a protocol to assess quickly the performance of any EIS instrument.

This technical note discusses the Accuracy Contour Plot (ACP). The ACP gives the user valuable information about a potentiostat’s EIS performance and accuracy.
