Description
The working electrode refers to an electrode that can cause significant changes in the concentration of the component to be tested in the test solution during the test. Common working electrodes include disk electrodes and replaceable electrode holders. Disk electrodes include glassy carbon electrodes,platinum disk electrodes,gold disk electrodes,silver disk electrodes,graphite electrodes,etc. Replaceable electrode holders include PTFE electrode holders, PEEK electrode holders, metal electrode holders, glassy carbon electrode holders, sample holders, etc.

Çalışma elektrodu denen elektrot, test sırasında test çözeltisinde test edilecek bileşenin konsantrasyonunda önemli değişikliklere neden olabilen bir elektrotu ifade eder. Yaygın çalışma elektrotları arasında disk elektrotlar ve değiştirilebilir elektrot tutucuları bulunur. Disk elektrotlar arasında cam karbon elektrotlar, platin disk elektrotlar, altın disk elektrotlar, gümüş disk elektrotlar, grafik elektrotlar vb. bulunur. Değiştirilebilir elektrot tutucuları arasında PTFE elektrot tutucuları, PEEK elektrot tutucuları, metal elektrot tutucuları, cam karbon elektrot tutucuları, örnek tutucuları vb. bulunur.
Glassy carbon electrode is one of the most widely used working electrodes, and it is a better inert electrode. Glassy carbon electrode has many advantages such as good conductivity, high hardness, high finish, high hydrogen overpotential, and wide polarization range. Its chemical properties are very stable, and it can be used as an inert electrode for direct anodic dissolution testing, and voltammetric determination of cathodes and variable valence ions. Using glassy carbon electrodes as the substrate, chemically modified electrodes can also be prepared.
There are four types of insulating rods for glassy carbon electrode jackets.
Glassy carbon electrodes are divided into straight type, L type, T type and detachable type. The straight glassy carbon electrode material faces vertically downwards, and the research material is coated on the glassy carbon material surface for testing. The reference electrode is matched with a curved luggin capillary salt bridge close to the material surface of the glassy carbon electrode, which can effectively reduce the R drop and improve the test effect.
Application note:
The disk electrode is immersed in the ion-conducting solution as a working electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the experiment, the electrode should be washed several times with ethanol. If the disk electrode was used as a current collector with other electrode material, or when there are visible traces of material absorption, it should be polished down to the mirror surface after the experiment is completed. Store the working disk electrode in the glass tube sealed with an O-Ring (all included in the package). An instruction on maintenance is provided in Electrode Polishing Kit product page.
