Product details

Model CS350 single channel potentiostat galvanostat can be used in battery study, energy and materials, such as fuel cell, Li-battery, coin battery, perovskite solar cells, supercapacitor etc. The most common electrochemical methods or battery test include Cyclic voltammetry, constant current charge and discharge, EIS etc.

It contains a fast digital function generator, high-speed data acquisition circuitry, a potentiostat and a galvanostat. With high performance in stability and accuracy with advanced hardware and well-functioned software, besides battery test, it is also a comprehensive research platform for corrosion, electrochemical analysis, sensor, life science and environmental chemistry etc.

SOFTWARE FEATURES

CS studio software provides users a versatile smoothing/differential/ integration kit, which can complete the calculation of peak height, peak area and peak potential of CV curves.

CS Studio software can achieve real time saving of the measuring data. The data can be automatically saved even in case of sudden power off.

CS studio kit has a built-in versatile timing policy for combined measurements, which can facilitate the automation of experiments and save time.

Battery analysis: charge & discharge efficiency, capacity, specific capacitance, charge & discharge energy etc.

EIS analysis: Bode, Nyquist, Mott-Schottky plot



TECHNICAL ADVANTAGES

1. Impedance (EIS)

CS350 potentiostat applies correlation integral algorithm and dual-channel over-sampling technique, and has strong anti-interference ability. It is suitable for EIS measurements of high-impedance system (>109Ω, such as coating, concrete etc.). It can also be used to obtain Mott-Schottky curve and differential capacitance curve. During test, the software can display real-time open circuit potential(OCP) without entering.

2. Polarization curve

It can complete linear polarization curve and Tafel plot measurements. The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to determine material’s pitting potential and protection potential and evaluate the its susceptibility to intergranular corrosion. The software employs non-linear fitting to analyze polarization curve, and can make fast evaluation of material's anti-corrosion ability and inhibitors.


3. Voltammetry

It can do the following electroanalysis methods: Linear Sweep Voltammetry(LSV), Cyclic Voltammetry(CV), Staircase Cyclic Voltammetry(SCV), Square wave voltammetry(SWV), Differential Pulse Voltammetry(DPV), Normal Pulse Voltammetry(NPV), AC voltammetry(ACV), Stripping voltammetry etc. It integrates calculation of peak area, peak current and standard curve analysis.

4. Electrochemical Noise

With high-resistance follower and zero-resistance ammeter, it measures the natural potential/current fluctuations in corrosion system. It can be used to study pitting corrosion, galvanic corrosion, crevice corrosion, and stress corrosion cracking etc. Through noise spectrum, we can evaluate the inducement, growth and death of metastable pitting and crack. Based on calculation of noise resistance and pitting index, it can complete localized corrosion monitoring.

5. Full floating measurement

CS350 potentiostat galvanostat uses full-floating working electrode. It can be used for autoclave electrochemical measurements, on-line corrosion monitoring of metallic components under the ground (rebar in concrete, etc.)

 

6. User-defined methods

CS350 potentiostat galvanostat supports user-defined combination measurements. The user can set cyclic  timing measurements of an electrochemical method or several methods.

We are able to provide API functions and development examples, which facilitates some users’ requirements for secondary development and self-defined measurements.
