BiPotentiostat/BiGalvanostat model CS2150M(without EIS) has two sets of built-in independent potentiostat /galvanostat. So it equals that you have 2 sets single-potentiostat in one chassis. Full floating module and electrical isolation design guarantee each channel is totally independent, which ensures accurate data. 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. CS2150M bipotentiostat is the real double-channel potentiostat. It uses Ethernet connection. Neither of the channels includes EIS function.
Applications
(1) Electrosythesis, electrodeposition (electroplating), anodic oxidation, electrolysis
(2) Oxygen reduction reaction(ORR), oxygen evolution reaction (OER), Hydrogen evolution reaction(HER), 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.
Typical applications for the bipotentiostat
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. CS2150M can be connected to any RRDE equipment.

Hydrogen Diffusion Test (HDT)
CS2150M 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.

Software Features
Cyclic voltammetry: 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.
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.
Real-time saving of data: The data can be automatically saved even in case of sudden power failure.
Combination/sequence test: it can achieve automation of experiments and save time. With the unique function of combination test, you can choose several experiments you want to run. Then you can make auto run of the pre-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.
