Gamry has officially launched their new Interface series potentiostats with the 1010. The Interface 1010 replaces the previous 1000 series and is available in the Interface 1010E, 1010B and the 1010T. The Interface 1010 boasts new features including a built-in temperature monitor using an RTD (Resistance Temperature Detectors) probe available on both models. The Interface 1010E Read more about Gamry Introduces New Interface Potentiostats[…]
Introduction For those interested in determining the characteristics of batteries, especially by discharging them to see their changes in impedance, Gamry Instruments offers the Reference™ 3000 potentiostat plus our 30k Booster. This combination of instruments is useful for running stress tests on batteries, by applying rapid, high-current pulses singly or repeatedly. As a cell, we Read more about High-current Pulses for Battery Research[…]
The Gamry Interface 1010 series Top 10 list: Channel-to-channel Isolation Gamry Instruments uses only low-profile components to drastically lower any electromagnetic interference, and places a conductive fence between channels. Ultimate Resolution Gamry Instruments starts with a 16-bit A/D converter for the best analog-to-digital resolution and add controllable noise filters to remove any noise in the Read more about The Gamry Potentiostat Difference[…]
Gamry’s multichannel potentiostat systems combine multiple research-grade instruments into a single, flexible system giving the ability to run each channel separately, in groups, or all at once. With the multichannel potentiostat you can combine up to eight Gamry potentiostats in a single system. This flexibility allows you to pick and choose how you want your Read more about Gamry Multichannel Potentiostat[…]
Warminster, Pa — Gamry Instruments, a leader in electrochemical impedance spectroscopy instrumentation, is proud to announce the launch of a new website designed to help researchers and academia find the right instrumentation for every application. The new website features a potentiostat selection tool, a first in the industry. This groundbreaking interface allows visitors to enter Read more about Gamry Instruments Launches New Website[…]
The Gamry Interface 5000 is the latest potentiostat from Gamry Instruments. This full-featured potentiostat/galvanostat is ideally designed for testing batteries, fuel cells and supercapacitors. What makes this potentiostat so unique? A Dual Electrometer. A second electrometer provides the ability to monitor both half cells in a typical three-electrode setup. With this feature, you can monitor both the anode and Read more about What makes the Interface 5000 Unique?[…]
Why Use Electrochemical Techniques for Corrosion Measurement? Corrosion is an electrochemical process. A broad range of electrochemical techniques have been developed specifically for corrosion measurement. Electrochemical techniques are fast. Electrochemical techniques are sensitive. Nevertheless, there are some Corrosion Engineers who don’t use electrochemical techniques…probably because they don’t understand them. Electrochemical Techniques and Corrosion Corrosion is Read more about Electrochemical Techniques for Corrosion Measurement[…]
Correct tuning of a potentiostat is required in order to produce accurate data. A diagnostic test can help determine if there are any problems with the instrument and should be the first step in troubleshooting. On the occasion when you have failure in a specific ‘sub test’ you have to decide what to do. Gamry Read more about Understanding the Calibration Information of Your Potentiostat[…]
The various parameters that are typically listed in the specifications of potentiostats are explained in this Technical Note originally posted by Gamry Instruments. There are many important factors that pertain to buying a potentiostat, and the old adage “The more the better” really does not apply when researching the potentiostat to fit your experiment. There Read more about Understanding Potentiostat Specs[…]

When I sit down to write about tricks of the trade and lessons learned in the practice of performing electrochemistry in autoclaves, my first thought is of all of those who preceded me in the adventure. This is only a partial and personal list: They are the researchers, facility engineers, supervisors, and technicians at Bettis and Knolls who paved the way. Some names that come to mind are Rick Garstka, Ted Druga, Bert Setterberg, Rudy Majcher, Jack Carr, Bob Rubino, Doug Thompson, Ken Granger, Rosemary Janik, Bill Archer, Garry Lynch, Irene Rosati, Mike Ochap, Dave Kedzierski, Keith Eklund, George Halbfinger, Mike Danielson, Yinfang Wang. Chief among those in other organizations who shared their stories was Digby Macdonald, who broke ground for many of us and was always eager to share his experiences.
Scope and Intent
This note will cover many topics that have only hot water in common. To fit within the space limitations of an application note, it will be a collection of lessons learned. As such, none of this is purely my own. There will be a stream of consciousness or memory and no part will be comprehensive. There may be future, detailed application notes to cover particular situations in depth, but they will await the questions that we hope this note will stimulate.
Some of the most common technical questions we hear have to do with iR compensation —
- Where does uncompensated iR come from?
- Do I need to use iR compensation with my experiment?
- How should I set up the iR compensation parameters?
- Why doesn’t iR compensation work on my system?
In this post we’ll attempt to answer these questions and to give you a basic understanding of iR compensation.
