In Situ Raman Electrochemical Cell is a specialized setup used in Raman spectroscopy to study chemical reactions and processes that occur at electrode surfaces under electrochemical conditions. Raman spectroscopy is a technique used to analyze the vibrational modes of molecules, providing information about molecular structure, composition, and interactions.   In an in situ Raman electrochemical cell, the setup integrates a Raman spectrometer with an electrochemical cell, allowing researchers to monitor changes in molecular composition and structure in real-time as electrochemical reactions take place at the electrode surface. This setup enables detailed insights into the mechanisms of electrochemical reactions, the formation of reaction intermediates, and the behavior of catalysts or electrode materials under working conditions. Key components of an in situ Raman electrochemical cell typically include: Electrochemical cell: This includes electrodes (working electrode, reference ele...

 According to the test requirements,  you can use the following content as a reference for selecting reference electrode. Different research systems can choose different reference electrodes: Neutral system: saturated calomel electrode or Ag/AgCl reference electrode Alkaline system: Hg/HgO reference electrode Acidic system: Hg/Hg2SO4 reference electrode Non-aqueous system: Non aqueous Ag+ reference electrode Compared with other reference electrodes, Ag/AgCl reference electrode is more sensitive to light.At the same time, the silver chloride electrode is also less affected by temperature than other types of reference electrode. If you choose calomel electrode, Hg2/HgSO4 electrode or Hg/HgO electrode, you can add a salt bridge under the electrode to protect the reference electrode and minimize the potential affected by temperature. Mercury Oxide Reference Electrode Hg/HgO PTFE Rod 6 * 60 mm is a good choice for the Alkaline system. you can find all the reference electrodes from ...

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...

Usually, the rapid seepage is caused by the internal pressure. After adding liquid, you can also invert the electrode to make the end ceramic core face up, and gently flick the PEEK rod to make the internal bubble float up. Insert it on a foam pad and let it stand for several minutes to release the internal pressure.                                                   If you buy a PEEK mercury oxide reference electrode, take some precautions when adding liquid. You can learn through the video on the product details page. https://www.dekresearch.com/mercury-oxide-reference-electrode-hg-hgo-peek-rod-%CF%864*60mm-3019.html

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 regu...

 How to choose the size of Reference Electrode? The diameter of   ERA131B [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ4*50mm Glass Rod ]   glass tube is 4mm, which is not the best choice for CHR221B2. The diameter of   ERA131A [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ6*70mm Glass Rod ] is 6mm, which is more suitable for CHR221B2.     L et me   briefly introduce this electrochemical cell for you.I attached two images, so you can see it clearly: Figure 1   is the default opening diagram of   CHR221B2 [ H-Type Sealed Electrochemical Cell 30ml 45ml ] .   The left side is the working electrode chamber opening diagram, and the right side is the counter electrode chamber opening diagram. As shown in the parameter diagram on our product details page, we place the working electrode and the reference electrode in a chamber, and are equipped with gas inlet and outlet holes [for inert gas protection and oxygen-free o...
