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.
Calibration of your potentiostat is necessary. Because of drifts of internal components over time, placement of the instrument in various environments, and slight differences in cable and cell geometry, your potentiostat’s measurements may change slightly. Calibration “resets” the potentiostat’s response to a signal. Types of Errors in Measurement
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.
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.
