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 also provides powerful non-linear fitting on Butler-Volmer equation of polarization curve. It can calculate Tafel slope, corrosion current density, limitation current, polarization resistance, corrosion rate. It can also calculate the power spectrum density, noise resistance and noise spectrum resistance based on the electrochemical noise measurements.
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)
CS 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.

Down: CV curves of PPy supercapacitor in 0.5 mol/L H2SO4
4. Electrochemical Noise
With high-resistance follower and zero-resistance ammeter, it measures the natural potential/currentfluctuations 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. Switchable floating and earthing mode
All CS potentiostats/galvanostats can switch between the floating and earthing modes, and this strategy is beneficial for studying electrochemical systems in which the working electrodes are intrinsically ground, such as autoclaves, in-site concrete structures and multi-working electrodes requiring isolation, etc.
6. High-bandwidth EIS
With the help of built-in digital FRA and arbitrary signal generator, as well as the high input impedance (1013 W), the CS potentiostat is particularly suitable for EIS measurements of high-impedance systems (such as coating, membrane, concrete, etc.)
Based on the DC bias compensation technique, CS potentiostats can conduct EIS tests under different charge/discharge states of batteries, making them suitable for ultra-low resistance systems, such as power batteries, fuel cells, water-splitting equipment, etc.
7. Multiple electrode configurations
CS potentiostats support 2-, 3-, or 4-electrode configurations and can measure the galvanic current via built-in zero resistance ammeter circuits.
8. User-defined sequence test
CS Studio 6.0 for Windows software supports user-defined sequence tests ("combination test"), which can facilitate automatic testing according to user-defined experiment sequences.
Sequence Test: corrosion tests
9. CST520 arrayed electrode mapper
Through CS2020B/CS2040B/CS2100B booster, the CS potentiostats can extend their output current up to ±20A/40A/100A, meeting the growing requirements in fuel cells, power batteries, electroplating etc
CS potentiostats can work with a CST520 arrayed electrode mapper to study the non-uniform corrosion of metal samples under deposits, coatings and anti-rust oils.
10. Software development kit (SDK)
All CS potentiostats run under the control of CS Studio 6.0 for Windows (CSS 6.0). The CSS6.0 supports third-party languages, such as LabVIEW, C, C++, C#, VC, Python and others. Some API general interfaces and development examples can be supplied with the CS potentiostats. Through the SDK, customers can implement user-defined test methods.
11. Real-time data saving
CSS 6.0 saves experimental data timely, even if the experiment is accidentally interrupted by a power failure or computer shutdown. CSS 6.0 supports several data formats compatible with Originpro and Microsoft Excel.
12. Versatile data analysis functions
CSS 6.0 provides robust functions, including various electrochemical measurements and data analysis. It can complete Tafel plot fitting, CV derivation, integration and peak height analysis, EIS equivalent circuit fitting, etc.
