Working Principle

The RST-5202 applies controlled electrical signals to an electrochemical cell and measures the resulting current, charge, or potential response. By varying the applied potential, pulse parameters, or measurement time, researchers can investigate electrode reactions and electrochemical processes.

Different techniques provide complementary information:

• Cyclic Voltammetry (CV): Examines oxidation and reduction behavior during forward and reverse potential sweeps.

•  Linear Sweep Voltammetry (LSV): Measures current as the applied potential changes in one direction.

• Chronoamperometry (CA): Records current over time following a potential step.

•   Chronocoulometry (CC): Measures accumulated charge over time.

•  Differential Pulse Voltammetry (DPV): Uses potential pulses to improve the discrimination of electrochemical signals.

•   Square Wave Voltammetry (SWV): Applies square-wave potential modulation for sensitive electrochemical measurements.

•  Bulk Electrolysis (BE): Supports electrochemical conversion of species in a sample under controlled conditions.

The resulting data can be used to characterize electrode materials, reaction kinetics, redox processes, and electrochemical analytical performance.
