H-Type In-Situ Raman Spectroscopy Cell With Double Light Window 30ml


In-situ Raman spectroscopy electrochemical cell is designed and manufactured for studying the in-situ spectra and morphology changes of electrode materials in electrochemical experiments. The working electrode is placed directly under the see-through window, so that the optical instrument can detect the working electrode from the quartz light window above the cell body. Commonly used instruments include optical microscopes, infrared microscopes, X-ray spectrometers, confocal Raman spectrometers, etc.

According to different experimental test requirements, the in-situ Raman spectroscopy electrochemical cell is divided into four types:

Single cell body with single light window type

Single cell body with double light window type

H type double cell body with single side light window type

H type double cell body with double side light window type

H-type double cell body with double-side light window type is an in-situ Raman characterization cell in which the working electrode and the counter electrode are separated in two chambers. It can be used to test the Raman spectroscopy detection of research materials including the CO2RR reaction process.


1.The main body of the in-situ Raman pool is made of polytetrafluoroethylene material, which is made by meticulous crafting.

2.The size of the working electrode chamber and the counter electrode chamber are both 80*80*30mm, the internal electrolyte solution part is a space of φ55*13mm, and the volume is 30ml. The diameter of the intermediate ion membrane exchange channel is 14mm.

3.The Raman cell is equipped with JGS2 quartz plate, the size of the quartz plate is φ41*1mm. The spectral application range of JGS2 optical quartz glass is 220-2500nm.

4.The standard working electrode of the Raman cell is a PEEK platinum sheet electrode holder, which can hold sheet materials such as carbon paper, metal sheet, metal mesh, foamed nickel, and conductive glass. The distance between the material surface and the quartz sheet is about 5mm. There are also detachable L-shaped glassy carbon electrodes or gold disk electrodes instead, which can reduce the distance between the material surface and the quartz plate to 0.5mm.

5.The standard counter electrode of the Raman cell is a platinum wire electrode, and the electrode size is φ0.5*37mm. There are also φ0.5*100mm or φ0.5*230mm platinum wire ring electrodes instead.

6.The standard reference electrode of the Raman cell is an Ag/AgCl reference electrode. There are also saturated calomel electrodes, Hg/HgO electrodes, Hg/Hg2SO4 electrodes and non-mercury Ag+ reference electrodes instead.

7.The working electrode chamber can hold the working electrode and the reference electrode. Two small holes are opened on both sides of the quartz light window, which can be used to pass air in and out or transport circulating electrolyte. The counter electrode is placed on the side of the counter electrode chamber, and two small holes are opened on both sides of the quartz light window, which can be used to pass air in and out or transport circulating electrolyte.

8.The Raman cell can be quickly assembled and disassembled, and it is easy to clean.

NOTICE:DekResearch's in-situ Raman spectroscopy electrochemical cell is basically suitable for various types of optical microscopes and Raman spectrometers in the world. When the focus distance of the instrument is different, please be sure to contact our technical team in advance

What is the CO2RR Gas Diffusion Flow Cell?

The CO2RR Gas Diffusion Flow Cell (CO2RR GDFC) is a type of electrochemical cell used in the conversion of carbon dioxide (CO2) to other chemicals through a process called the CO2 reduction reaction (CO2RR). It is similar in design to the Gas Diffusion Flow Cell (GDFC) used to measure gas permeability, but it is specifically designed to facilitate the electrochemical reduction of CO2. The CO2RR GDFC consists of a small, sealed chamber with two compartments separated by a thin, gas-permeable membrane. One compartment is filled with a CO2-containing gas mixture, while the other compartment contains an electrolyte solution and a catalyst material, such as copper or silver, which facilitates the CO2RR. The two compartments are separated by the gas-permeable membrane, which allows CO2 to diffuse from the high concentration compartment to the low concentration compartment. The CO2RR is driven by an electric potential applied across the two compartments, which induces the reduction of CO2 int

What is the Gas Diffusion Layer (GDL)?

      The GDL is a porous structure made by weaving carbon fibers into a carbon cloth (e.g. GDL-CT and ELAT) or by pressing carbon fibers together into a carbon paper.  Many of the standard GDLs that are produced today come with a Micro Porous layer (MPL) and hydrophobic treatment (PTFE).  The MPL and PTFE help with the contact to the membrane and with water management.  The MPL typically provides a smooth layer with plenty of surface area for catalyst and good contact with the membrane.  The MPL often uses PTFE as a binder that increases hydrophobicity, which helps keep the water within the membrane from escaping – drying out the membrane and causing higher resistance (lower performance).  There is often an additional PTFE coating on the MPL surface to further augment this. What Exactly Does a Gas Diffusion Layer (GDL) Do? GDL essentially acts as an electrode that facilitates diffusion of reactants across the catalyst layered membrane. The surface area and porosity of the GDL is what

How to do when the mercury oxide reference electrode broken?

Q: How to do when the mercury oxide reference electrode broken? A:  If the electrode is broken, please be sure to operate in accordance with the laboratory hazardous chemical treatment method to avoid the diffusion of mercury oxide, which is a toxic material. Description of the mercury oxide reference electrode: The mercury-mercury oxide(Hg/HgO) reference electrode is mainly used in alkaline solutions. It is an electrode composed of metallic mercury and its insoluble salt HgO and 1M KOH solution. Its electrode potential is 0.098V (25°C). The salt bridge of the Hg/HgO reference electrode is made of glass and PTFE, and the size is φ6*70mm. This size can be matched with various types of Dek Research electrochemical cells. Special attention should be paid to maintenance and storage when using the Hg/HgO reference electrode. The substance containing mercury oxide is a toxic substance, and the salt bridge solution is corrosive. Please strictly abide by the relevant laboratory safety regulati
