Constant Potentiostat is a commonly used basic and important instrument for electrochemical testing of metal corrosion. It can not only be used in a variety of electrochemical tests, but also can be used for metal corrosion, electrochemical protection, electrolysis and electrosynthesis, electroplating, metallurgical etching, phase analysis and other research areas and production practices, but also for a variety of current waveform polarisation measurements. Because of its different uses appear many different types of constant potential meter. Such as for the rotating ring a disc electrode system research double constant Potentiostat: for small signal test low noise constant Potentiostat: for fast transient electrode process research fast corresponding constant Potentiostat as well as suitable for electrochemical protection and other electrochemical processing of silicon controlled constant Potentiostat and so on.
Solubility: in electrochemical experiments, it is usually necessary to dissolve the sample in a solvent, so as to facilitate the electrode and sample contact and reaction, to avoid precipitation and solid particles on the surface of the electrode. Sample purity: The sample should be as pure as possible to avoid interfering with the experimental results. Sample content: too high or too low sample content may lead to distortion of the experimental results. The stability of the sample: electrochemical reaction is usually a dynamic process, the composition and concentration of the sample may change over time.
