CS2350M dual potentiostatBuilt in two sets of constant potential/constant current meters, each with an auxiliary, working, and reference electrode output, and coordinated by CS Studio testing software to output potential/current. CS2350M is a true dual channel electrochemical workstation.
Specifically applied to:
1. Dual channel independent use, capable of conducting two sets of routine electrochemical tests simultaneously;
2. Dual channel combination can be used for electrochemical analysis of four electrode working systems, especially in the collection of intermediate products in oxygen reduction (ORR) and metal hydrogen diffusion testing.
technical advantage
CS2350M dual potentiostatNot only does it have CS single channel series high-precision, wide range, and * data analysis and processing functions, but it also innovatively breaks through on the basis of existing products. The CS2350M dual channel hardware design can meet the testing requirements of two experimental systems, and the combined programming function of the software greatly improves the efficiency of the experiments.
Typical Case
1. Dual channel independent testing
By using a dedicated battery testing clip and combining it with software's programming capabilities, we aim to provide users in the battery energy field with a more efficient and intelligent testing experience.

2. Cooperate with the rotating ring disk electrode(RRDE)Used for studying redox systems:
While measuring the polarization curve of the circular electrode, the ring voltage is set to a constant potential to control the circular electrode at a fixed polarization potential, in order to detect the reaction intermediates generated on the circular electrode. This method has also become a typical fluid dynamics method for detecting reaction intermediates and studying electrode reaction mechanisms. The electron transfer number of oxygen reduction reaction and the corresponding yield of hydrogen peroxide (intermediate product) can be measured by the formula:

Among them, I knowdiskAnd IringThe electrode collection efficiency N is determined by the parameters of the disk ring electrode (constant), which are the measured disk current and ring current, respectively. Substitute the test results into the above formula to obtain the actual electron transfer numbers n and H of the reaction2O2The proportion of (%).

3. Hydrogen diffusion test in metals:
Two constant potential devices are used in conjunction with the Devnathan Stachurski double electrolysis cell. The diffusion coefficient and hydrogen flux of hydrogen atoms in the metal are calculated by measuring the cathodic hydrogen charging in the left electrolysis cell and the anodic oxidation current of hydrogen atoms in the right electrolysis cell.
