Setup of the Electrochemical Cell
The setup of the electrochemical cell, including the various electrodes, cabling, shielding and the cell itself is critical to making precision measurements. The notes below are useful references for checking and optimizing the setup at the end of the cable. Click on a link below to view the Application or Technical Note.
It's very important for optimum potentiostat performance that the impedance of the Reference Electrode in your cell is low!
Vycor® is often used at the end of a reference electrode or a bridge tube to allow electrical, ionic conductivity between the bulk of the solution and the internal filling solution, while preventing large scale convective mixing of the solutions. Vycor, or "thirsty glass" is a porous glass with a fairly low leak rate.
