两电极, 三电极和四电极实验介绍
Electrochemical experiments range from simple potentiostatic (chronoamperometry), to cyclic voltammetry (potentiodynamic), to complex AC techniques such as impedance spectroscopy.
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.

It is a well-known secret (there’s an oxymoron for you!) among electrochemists that a Faraday cage is used to reduce noise. While this “secret” is fairly widely known in electrochemistry circles, you would be hard-pressed to find good information regarding the use and function of Faraday cages in electrochemistry textbooks. In fact, a cursory inspection of the many books on our bookshelves here at Gamry produced one result in Electrochemistry for Chemists: “[Voltammetry at microelectrodes] usually requires that measurements be done in a Faraday cage (a shield against electronic noise).”[1]
