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.
The Calibration Cell is a printed-circuit board used for calibration and troubleshooting of your Gamry Instruments potentiostat, and is supplied with every Gamry Instruments potentiostat. Each potentiostat also comes with an AC dummy cell.
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.
