How to choose the size of Reference Electrode?

 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.  


Let 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 operation]. We placed a counter electrode in another chamber, which is also equipped with gas inlets and outlets.Generally, we default that the electrode hole is matched with an electrode with a diameter of 6mm for sealing, and the gas hole is sealed with a diameter of 3mm.



Figure 2 is our design concept for the sealing hole. All electrodes or PTFE tubes are sealed by tightening the sealing screw and extruding the fluorine rubber O ring to block the gap between the electrode and the electrode hole or the gap between the PTFE tube and the gas hole. Therefore, assuming your electrode diameter is 6mm, we will open the sealing hole M12-6.7mm with O-ring for sealing.

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...

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 c...

In Situ Raman Electrochemical Cell

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...
