The cell features separate gas inlet and outlet ports for the cathode and anode sides, requiring external gas supply connections. The single-crystal silicon window functions as the working electrode and must remain free of contamination to preserve optical and electrochemical performance.
- Gas inlet/outlet requirement: The cell must be connected to an external gas management system to control atmosphere in both compartments.
How does the internal reflection configuration of the AF-IR-HIN cell affect the selection of the working electrode material?
The internal reflection design uses the infrared window substrate as the working electrode basis. In the standard configuration, the working electrode is a single-crystal silicon window substrate, uncoated. This creates a trade-off between electrochemical activity and optical transmission because the electrode material must also function as an effective IR window. For applications requiring different electrode materials, customization is available upon request per the product description.
What reference electrode is compatible with this in-situ IR cell and what are its limitations?
The standard reference electrode provided is Ag/AgCl. This electrode is well-suited for aqueous electrolytes but may have limited compatibility with non-aqueous or organic solvent systems. The product description does not specify alternative reference electrodes in the standard configuration, so users should confirm compatibility with their electrolyte system and potential range with the manufacturer before ordering.
What are the gas handling requirements for operating the H-type in-situ infrared cell?
The cell features gas inlet and outlet ports available for both the cathode and anode sides, allowing independent purging of each chamber. With a total cell volume under 20 mL, gas flow rates must be controlled to avoid overpressure while maintaining an inert atmosphere. Proper gas handling is essential to prevent atmospheric contamination of the infrared measurement, but the product description does not specify optimal flow rates or pressure limits.
The H-Type Membrane-Replaceable In-situ Infrared Cell (Internal Reflection) is a specialized electrochemical cell designed for operando infrared spectroscopy, using a single-crystal silicon window as both the IR substrate and working electrode, with separate gas ports for cathode and anode chambers.
Positive
- Internal reflection with silicon working electrode: The internal reflection configuration uses the single-crystal silicon window as the working electrode, enabling direct in-situ IR monitoring of electrode surface reactions without additional reflective coatings.
- Separate gas ports for cathode and anode: Gas inlet and outlet ports on both sides allow controlled gas purging or reactant delivery to each chamber independently, supporting gas-involved electrochemical studies.
Trade-offs
- Uncoated silicon window limits spectral range: The standard uncoated single-crystal silicon window has an IR transmission cutoff below approximately 1500 cm⁻¹, restricting detection of lower-energy vibrational modes without custom window coatings.
- Small cell volume constrains electrolyte volume: With a cell volume under 20 mL, the design limits electrolyte capacity and may require frequent replenishment or careful degassing for extended experiments.
