Introduction: The counter electrode is used to pass an electric current to achieve polarization of the research electrode. When studying cathodic processes, the auxiliary electrode is used as the anode, and when studying anodic processes, the auxiliary electrode is used as the cathode. The area of the auxiliary electrode is generally larger than that of the research electrode, which reduces the current density on the auxiliary electrode and makes it basically not polarized during the measurement process. Therefore, platinum black electrodes are often used as auxiliary electrodes, and can also be used in the research medium. Remaining inert metallic materials such as Ag, Ni, W, Pb, etc.; in specific cases, specific electrodes are sometimes used. Sometimes for the convenience of measurement, the auxiliary electrode can also be made of the same metal as the research electrode. The advantages of the gold sheet electrode are good conductivity, high chemical stability, low thermal expansion coefficient, hard texture, good air tightness, and a wide range of potential applications (about -1 ~ 1V, relative to saturated calomel electrodes), can be prepared It can be formed into electrode shapes such as cylinders and discs, and it can also be used as a matrix to make mercury film glassy carbon electrodes and chemically modified electrodes. It has been widely used in electrochemical experiments or electroanalytical chemistry. Technical parameter: Gold sheet thickness: 0.1mm ~ 1mm, length and width optional.
