Measurement of Small Electrochemical Signals

Posted by gamry on January 29, 2018

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.
