Electrochemical Workstation
BACK
Standards:
Applications:
The electrochemical workstation is widely used in electrode process research, chemical power sources, electroplating, electrolysis, electroanalytical chemistry, metal corrosion studies, and the determination of electrochemical protection parameters, among other fields.
Product Information:
The electrochemical testing system consists of an Electrochemical Workstation (including potentiostat/ galvanostat and electrochemical impedance spectroscopy modules) and control and data analysis software.The electrochemical workstation includes four main functional modules: electroanalysis, corrosion, electrochemical impedance spectroscopy (EIS), and energy modules, enabling the implementation of all major electrochemical measurement techniques.
Product Features
The hardware of the electrochemical workstation is built with high-quality integrated circuits, featuring high control precision, fast response speed, stable performance, compact structure, and a high degree of automation. The system incorporates a high-speed control unit and a high-precision 18-bit dual-channel A/D converter, enabling high-resolution data acquisition. Communication with the PC is achieved via Ethernet.
The electrochemical workstation adopts a high-speed data processor, providing fast and high-precision electrochemical measurements. Installation and configuration are simple, with Ethernet connectivity (supporting plug-and-play functionality) and low startup cost. A high-speed digital-to-analog conversion board enables the generation of instantaneous current and voltage pulses, producing various complex electrochemical test waveforms and supporting fully synchronized voltage and current measurements.The system supports a four-electrode configuration, allowing flexible testing of both high- and low-impedance electrochemical cells. It uses precise single-sine technology to ensure that the amplitude applied to the electrochemical cell remains consistent with the set value, maximizing measurement resolution under both linear and stable conditions.
The electrochemical workstation software is powerful and user-friendly, with simple experimental setup. It supports automated batch testing for potentiostatic, galvanostatic, and impedance experiments.The software provides functions such as information prompts and external system
integration, as well as data copy/paste and export capabilities, allowing easy data processing and transfer to external analytical software beyond the workstation platform.
Multiple graphs and datasets can be displayed in a single window. The built-in data analysis module supports comprehensive data processing and curve fitting functions, including linear fitting, peak analysis, polarization resistance (Rp) fitting, Tafel fitting, and electrochemical impedance spectroscopy (EIS) fitting.
