Great results, reproducible results, easy to use
coatings
Gamry potentiostats are very easy to use, the software is intuitive. Reproducible results can be found. The equipments have a wide application range. In my case, in the evaluation of polymer coatings for the oil & gas industry, it has been an effective tool. The impedance ranges are wide, making evaluation easy.

The Reference 620 Potentiostat is the Cadillac of potentiostats!
Corrosion protection performance of organic coatings
I run potentiostatic electrochemical impedance spectroscopy with this equipment. The data are extremely high quality. The technique and potentiostat are very sensitive. The interface is user-friendly, and the software is easy to maneuver. I have not had to call Gamry for after-sales care, so I gave the item 3 stars in this category for neutral. Based on my phone calls with Gamry regarding other product inquiries, however, I would expect excellent after-sales care.

Workhorse of CV and EIS
Electrode kinetics using cyclic voltammetry
I have been doing fundamental 3E electrochemistry for about 10 years now, have used CHI, Biologic, Gamry and Princeton instruments. For CV and EIS, you really can't do better than the reference 620. Signal to noise is fantastic, scripting is possible (and scientists at gamry will write scripts for you if you need something unavailable!), and the EIS data is publication quality everytime. While the price is higher than Biologic, this Pstat surpasses all others for 3E fundamental electrochemistry!

Good ease of use, after sales support in India need lots of work
Electrochemistry measurement & corrosion rate
We have almost 10 potentiostats we use in our lab. In terms of ease of use, I would rate this as one of the easiest. The bigger challenge is after sales support in India, we have been following up on a problem from many months, which is not yet resolved. The technical team also takes a lot of time to come back and fix the issue. Speaking frankly, if I find a better alternative to Gamry with better service support, I will be switching to it for sure.

EIS of difficult samples
Electrochemical Impedance Spectroscopy (EIS) is a technique that can be applied to various systems. This white paper is designed to give helpful information for systems that are a bit more challenging to measure. Typical examples would include barrier coatings, very corrosion-resistant materials, and very low impedance samples such as large supercapacitors (on the order of hundreds or thousands of Farads).
EIS of organic coatings and paints
This application note describes the effects that a potentiostat can have on electrochemical impedence spectroscopy (EIS) measurements of coated metals. Discover recommendations for getting meaningful EIS spectra on coating systems that are typically difficult to measure.
Setting up two, three and four electrode experiments
Electrochemical experiments range from simple potentiostatic (chronoamperometry) to cyclic voltammetry (potentiodynamic), to complex AC techniques such as impedance spectroscopy. Moreover, each individual technique may have multiple possible experimental setups, often with a best option. This note discusses one aspect of these setups: the number of electrodes (or probes) used.

This application note explains how electrochemical impedance spectroscopy (EIS) can be perfomed using Gamry Instruments not only on flat samples in electrochemical cells, but also on curved parts not immersed in a liquid medium.
How to Set Up Your Electrochemical Experiment: Two-, Three-, and Four-Electrode Experiments
This applcication note explores and explains the setup of Gamry Instruments potentiostats in a series of electrode experiments. This note is applicable to any Gamry potentiostat, as well as some others.
Accuracy Contour Plots – Measurement and Discussion
Electrochemical Impedance Spectroscopy (EIS) is an indispensable, valuable, and versatile analytical tool for resolving electrochemical processes. This technical note discusses the Accuracy Contour Plot (ACP). The ACP gives the user valuable information about a potentiostat’s EIS performance and accuracy, enabling the user to compare the EIS capability of any potentiostat.
Testing Electrochemical Capacitors Part 3: Electrochemical Impedance Spectroscopy
This application note is Part 3 of the series describing electrochemical techniques for energy-storage devices. It discusses basics of Electrochemical Impedance Spectroscopy (EIS) and introduces Gamry’s EIS techniques by measurements on single electrochemical capacitors (ECs) and stacks.
The Fundamentals of the Potentiostat
In this application note, learn about the fundamentals of the potentiostat - an electronic instrument that controls the voltage difference between a working electrode and a reference electrode. Both electrodes are contained in an electrochemical cell. The potentiostat implements this control by injecting current into the cell through an auxiliary, or counter, electrode.
