Tafel plot can be obtained. The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to obtain material’s pitting potential and protection potential and uate the its susceptibility to intergranular corrosion. The software uses non-linear fitting to analyze polarization curve, and can make fast evaluation of material’s anti-corrosion ability and inhibitors..png)

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. In CV technique, during the data analysis, there is function of selecting exact cycle(s) to show. You can choose to see a cycle or some cycles as you want. You can also export data or vector graph of an exact cycle or several cycles..png)
Tafel plot and corrosion rate:
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.
Battery Test and analysis:
charge & discharge efficiency, capacity, specific capacitance, charge & discharge energy.
EIS analysis: Bode, Nyquist, Mott-Schottky plot
During EIS data analysis, there is built-in fitting function to draw the custom equivalent circuit.
Real time saving of data: The data can be automatically saved even in case of sudden power off.
Combination test: it can facilitate the automation of experiments and save time. With the unique function of combination test, you can choose several techniques, and set the wait time, the start time, and the cycles. Choose the experiments you want to run. Then you can make auto measurement of the set experiments as you want without having to wait in the lab. This function is especially useful if you have multi experiments to run and save your time greatly.
Data open: You can open the data files by txt format in notepad. Data can also be opened in Origin
