Some of the notes below cover potentiostats in general and others are for Gamry Instruments systems specifically. Click on a link below to download the PDF version of the Application or Technical Note.
This technical note is intended to help you better understanding the functionality 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.
The purpose of this Application Note is to show the reader a simple experiment where we reduce Cu2+ onto an Au electrode and then oxidize Cu back off. We will then use the result to calculate a calibration factor for the crystal. Conversely, we will show you how to calculate the molar mass of the species deposited using a calibration factor.
This application note describes the software changes that you can make to slow down a Gamry Instruments’ potentiostat. Slowing down the potentiostat can improve its stability. These changes presume a working knowledge of Gamry Instruments’ Explain™ scripting language.
Of all the components of a Gamry system, the Cell Cable is the one that is constantly being flexed and exposed to corrosive environments. This test may take a couple of minutes, but if it identifies a problem, it will be time well-spent.
When performing experiments with dye solar cells, light is focused on the cell and its current response is measured. The generated current depends strongly on the intensity of the light. 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.
This Application Note may be difficult to follow unless you have some familiarity with electrical terms such as voltage, current, resistance, frequency, and capacitance. If you feel your knowledge in this area is lacking, we suggest review of a very basic electronics or physics book.
This application note is meant to provide you with several tips and techniques for improving potentiostat stability. Potentiostats can become unstable for several reasons. Improving the stability may require trying several different techniques.
