Abstract: Electrochemical analysis applies the electrochemistry principle and technology. It is an analytical method based on the relation between the composition and content of the analyte solution and its electrochemical properties within the chemical cell. The commonly used instruments possess electrochemical workstation with multiple functions. In paper the electrochemical workstation functions of a broadband dielectric electric spectrometer, including the instrument structure and composition, principle of the instrument, advanced functional applications and the unique advantage of the advanced instrument itself are introduced.
