2-Channel Potentiostat Double Channel Bipotentiostat CS2350M With Impedance
BiPotentiostat/BiGalvanostat with built-in EIS model CS2350M has two sets of built-in independent potentiostat /galvanostat. So it equals that you have 2 sets potentiostat in one instrument. Full floating module and electrical isolation design guarantee each channel is totally independent, which ensures accurate data. Each set provides full electrochemical techniques including EIS. Experiments can be conducted simultaneously in each channel. Besides this, the two channels can jointly complete experiment of two-working electrode system such as RRDE and Hydrogen diffusion. CS2350M bipotentiostat is the real double-channel potentiostat. It uses Ethernet connection. EIS module is included in both channels.
Applications
(1) Electrosythesis, electrodeposition (electroplating), anodic oxidation, electrolysis
(2) Electrocatalysis such as Oxygen reduction reaction (ORR), OER,
HER, CO2 reduction.
(3) Li-ion battery, solar cell, fuel cell, supercapacitor, advanced
function materials, sensor, etc
(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 (ORR) study: while measuring the polarization curve of disk electrode in the main channel, apply a constant polarization potential on the ring electrode, and thus detect the intermediate products on the disk electrode. RRDE test becomes the typical method for ORR study. CS2350M can be connected to any RRDE equipment.
Hydrogen Diffusion Test (HDT)
CS2350M bipotentiostat is combined with H-cells. By measuring current of cathode hydrogen charging and hydrogen atoms anode oxidation, it can further calculate the diffusion coefficient of hydrogen atoms in metal and hydrogen flux.
Faradaic efficiency test
In electrocatalysis, the Faradaic efficiency is measured to evaluate the performance of the catalyst. The cable connection is shown in below picture. A constant current will be applied on the disk and occur OER and produce oxygen. A constant voltage is applied on the ring and it occurs ORR and consume oxygen. The Faradaic efficiency can be calculated based on disk current and ring current.
