The Leader in Electrochemical Impedance Spectroscopy

Here to help

Gamry Instruments prides itself on performing accurate EIS.

We publish an Accuracy Contour Plot (ACP) for every instrument we sell. ACPs describe a region of accuracy over a given range of impedances and frequencies under a defined set of conditions.

Generating Accuracy Contour Plots are important in understanding the ranges and limitations of our instruments when performing EIS under typical conditions.  They also can change depending on cable length and signal amplitude.

The lower impedance limit is useful to know when examining energy storage and conversion devices while the upper impedance limit is useful for corrosion-resistant materials and well-coated samples.

Market Applications we serve

Electrochemistry Applications

Electrochemical Corrosion Gamry has been at the forefront of electrochemical corrosion testing for instruments with ease of use and reduced acquisition for research.	Battery Testing Gamry’s floating potentiostats are well suited for battery testing of materials from coin cells to large format cells.  We even have a system for stack testing.
Fuel Cells Gamry provides several systems for fuel cell development and testing which include tools designed to improve data analysis and workup.	Supercapacitors Testing for supercapacitors is very similar to testing of batteries, just on a faster time scale.  We have a number of recommended setups for the supercapacitor researcher.
Sensors Most sensors are amperometric or impedimetric.  Gamry makes it easy for researchers to generate and analyze data from either of these sensors.	Photovoltaics Photovoltaic researchers looking for a complete solution will find Gamry's IMPS/IMVS quite capable of helping the researcher find the answers they need.
Biological Electrochemistry Gamry provides a suite of flexible electrochemical tools to generate new potential waveforms needed for cutting edge biological applications.	Electrosynthesis A process involving the use of a potentiostat to drive current through an electrochemical cell forcing a chemical reaction producing a desired product
ElectrolysisElectrolysis A process that involves the use of a galvanostat to push electrical current through an electrochemical cell to drive a non-spontaneous chemical reaction.	Paints and Coatings Our paints and coatings customers have told us that ease of use and reduced acquisition time are the most important features for their research.
