The CS2350 dual unit electrochemical workstation is a general potentiostat/ galvanostat/ FRA designed forgeneral purpose electrochemical measurements. The instrument contains a fast digital function generator, high-speed data acquisition circuitry, a potentiostat and a galvanostat (select models). The potential control range is ±10V and the current range is ±2A. The instrument is capable of measuring current down to picoamperes. The instrument is capable of a wide variety of electrochemical techniques, and is available with integrated simulation and fitting software functions for both impedance and cyclic voltammetry. These features provide powerful tools for electrochemical mechanistic studies.
CS2350 bipotentiostat is developed on regular single- channel CS350. There are two independent sets of built-in potentiostat/galvanostat. For each set of potentiostat, there is a set of counter/working/reference electrode. CorrTest software controls the output potential and current.
CS2350 consists of main channel and slave channel. The slave channel applies floating mode to control the potential and current of WEII. The potential and current of WEII can independently remain constant. Tests (independent of WEI) such as linear scan and cyclic voltammetry sweep can be conducted.
Apart from all functions that single-channel CS350 workstation has, CS2350 can be especially used to do RRDE and HDT.
Application
RRDE (Rotating ring-disk electrode)
While measuring the polarization curve of disk electrode, keep the ring electrode at a fixed polarization potential, and thus detect the intermediates of reaction on the disk electrode. It becomes the typical fluid dynamics method that detects reaction intermediates and studies electrode reaction mechanism.
HDT (Hydrogen diffusion Test)
The bipotentiostat is combined with Devnathan-Stachurski cell. By measuring cathode hydrogen charging current (the left cell) and anode oxidation current of hydrogen atoms (the right cell), it can further calculate the diffusion coefficient of hydrogen atoms in the metal and hydrogen flux.
