Electrochemical Operando Cell


Electrochemical operando Cell (EC-RAIR) is a unique operando cell for Raman and infrared spectroscopy characterization in the electrochemical field. This operando cell is mainly used to collect the Raman or IR spectrum online for the catalysts during their electrochemical reaction. It can be applied into the fields of chemistry, materials, and other related fields, especially suitable for the basic electrochemical research. And it can be expended to more functions if users want.

Main features:

1. The operando cell is a customized electrochemical cell, which can be applied into Raman or IF characterization (mainly for the reflective modes).

2. The operando cell has a minimum working distance with 1mm, to meet the general Raman and infrared testing;

3. The operando cell is a three-electrode system, including the working electrode, reference electrode and the counter electrode, the working electrodes are two different special glassy carbon electrodes;

4. The reference electrode and the counter electrode, can be replaced depending on the users’ demand, the standard is platinum wire electrode and silver chloride electrode ;

5. The sample size can be adjusted from 3 to 10mm with a maximum thickness of 2mm;

6. Optical window with a size of φ36mm, has several different choices, including quartz, sapphire, and other IR windows;

7. Inlet and outlet valves are installed in the main cell to meet the requirements of different atmospheric conditions and tightness of electrochemical reactions;

8. The whole installation of the device is simple and fast, and the cleaning of each component is convenient.


Optional accessories: optical quartz, sapphire, fluoride and other IR windows.
