Of all the components of a Gamry system, the cell cable is the one that is constantly being flexed and exposed to corrosive environments.

The individual conductors in the cell cable of the potentiostat are made up of coaxial cables. The outer conductor in a coaxial cable is used to shield the signal of interest

Potentiostats are often required to work near the limits of their measurement ability. The Gamry Instruments Reference 600 can resolve current changes. Measurements of small currents place demands on the instrument, the cell, the cables, and the experimenter. Many of the techniques used in electrochemistry of larger currents must be modified when used to measure pA and fA currents. In many cases, the basic physics of the measurement must be considered.

The purpose of this Application Note is to demonstrate a simple experiment to reduce Cu2+ onto a gold electrode and then oxidize Cu back off.

Among the uses for Gamry Instruments’ eQCM 10M electrochemical quartz crystal microbalance is studying film growth. Here is an example of film growth affecting electrochemical behavior of certain electrodes.

In this technical note, we look at the less well-known dual-electrometer feature in our Interface 5000E potentiostat. The dual electrometer allows the user to make a second voltage measurement in addition to the one made by the potentiostat.

Some initial background information describes the general issue of iR errors. This application note presumes that you have a basic understanding of potentiostat operation.

Some researchers want to be able to apply or measure voltages larger than 12 V. One example of the need for larger potentials is battery testing, while another might be CV inside small microfluidic channels.

This technical note is intended to help you better understanding the specifications of potentiostats. Various parameters that are typically listed in specification sheets of potentiostats are explained. In addition, it is shown which parameters are more relevant for specific applications and where you should pay attention.

In order to calculate the efficiency of a solar cell, the optical power of the incident light has to be known. This technical note explains how to measure and calculate the optical power of your light source.
