The Risks of Using Unshielded Cables

Posted by gamry on November 14, 2018

Cell cables are an integral part of your potentiostat and can have a large effect on full measurement capabilities of the complete system. They provide connection between the potentiostat itself and your electrochemical cell.

Calibration of Your Potentiostat

Posted by gamry on September 7, 2018

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

Checking the Integrity of a Gamry Cell Cable

Posted by gamry on June 26, 2018

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.

Calibration of a Gold-coated Quartz Crystal

Posted by gamry on March 23, 2018

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.
