Products Description
The XW-CS-2350 dual potentiostat is an improved version of the single channel XW-CS-350 potentiostat/galvanostat, with two built-in potentiostat/galvanostat sets. The two channels can independently/simultaneously perform the same or different experiments.
If the user only chooses to use the main channel, XW-CS-2350 will change to XW-CS-350. In addition to all the functions of the XW-CS-350 single channel potentiostat, the XW-CS-2350 is also particularly suitable for RRDE and HDT.
Technical Parameters
| Applications |
| ( 1) Electrosythesis, electrodeposition (electroplating), anodic oxidation, electrolysis |
| (2) Oxygen reduction reaction(ORR), oxygen evolution reaction (OER), Hydrogen evolution reaction(HE R), carbon dioxide reduction. |
| (3) Energy and materials (Li-ion battery, solar cell, fuel cell, supercapacitor), advanced function materials, and sensor. |
| (4) Corrosion behavior of metals, and anti-corrosion evaluation |
| (5) Fast evaluation of inhibitor, water quality stabilizer, coating, and cathodic protection efficiency. |
| Rotating ring-disk electrode(RRDE) |
| Oxidation/reduction reaction system: while measuring the polarization curve of disk electrode, keep the ri ng electrode at a fixed polarization potential, and thus detect the intermediates of reaction on the disk ele ctrode. It becomes the typical fluid dynamics method that detects reaction intermediates and studies elec trode reaction mechanism |
| Hydrogen diffusion test(HDT) |
| Two potentiostats are combined with Devnathan-Stachurski (dual cell). By measuring cathode hydrogen charging (the left cell) and anode oxidation current of hydrogen atoms (the right cell), it can further calcul ate the diffusion coefficient of hydrogen atoms in the metal and hydrogen flux. |
