Multi-Channel Electrochemical Workstation-IVIUMnSTAT

IVIUMnSTAT multi – channel electrochemical workstation is a stable – performance potentiostat/galvanostat, capable of providing users with electrochemical environments under various conditions. For special electrochemical measurement methods and measurement conditions, requirements can be met by adding various functional modules.

Functional Features

Cyclic voltammetry and linear sweep: Current averaging, controlled – current method, ohmic drop correction, corrosion rate analysis, and Tafel curve analysis.

Chronoamperometry, chronopotentiometry, and chronocoulometry: 1 to 255 different potentials/current values and ohmic drop compensation can be set, allowing for at least 65535 cycles of measurement.

Mixed mode: At least 255 segments can define applied signals, including potential steps, current steps, potential sweeps, current sweeps, open – circuit potential, controlled resistance and resistance sweeps; real – time impedance measurement from 10 Hz to 250 kHz; all steps and sweeps can monitor resistance and capacitance simultaneously during potential and current measurements; the entire process can be finite or continuously repeated.

Electrochemical noise: With electrochemical noise measurement and analysis functions.

AC impedance measurement and analysis functions: Can perform controlled – potential or controlled – current frequency sweeps; Mott – Schottky curves; electrochemical frequency modulation EFM; frequency range from 10 μHz to 250 kHz.

Photoelectrochemical functions: Through software’s I~V curve fitting function, short – circuit current (Isc), open – circuit voltage (Eoc), maximum power point (Pmax), and fill factor (FF) and other relevant parameters can be calculated. Connect to the photoelectrochemical module for measuring solar energy materials’ light – modulated AC impedance IMPS/IMVS.

Can connect to a WIFI module to achieve wireless connection between computers and instruments; can remotely control equipment in the laboratory through the network in the office.

Batch processing functions: Users can freely combine multiple measurement procedures and automatically perform them in sequence.

Open – source programs: Provide open – source programs, allowing users to write various programs through different programming languages, such as C++, Delphi, VB, etc., and more conveniently remotely control instruments through LabVIEW software.

Has 2 analog signal input channels and 1 analog signal output channel.
