In Situ Raman Spectroelectrochemical Cell (2H Exchange Membrane Type), Model: EC-RM2

Description

Product Overview

The EC-RM2 provides direct Raman access to a sheet-type working electrode through a quartz optical window while maintaining three-electrode electrochemical control. Its two-chamber, replaceable-membrane design separates the cathode and anode chambers, minimizes anodic interference at the cathode, and supports both syringe filling and external electrolyte circulation.

Key Features

• Direct Interface Observatio: Positions the working electrode directly below the quartz window for in situ optical observation.
• Replaceable Membrane Separation: Separates the cathode and anode chambers using a replaceable ion-exchange membrane.
• Reduced iR Drop: Places the reference and working electrodes in the same chamber to reduce iR drop.

Instrument Compatibility

• Raman System Compatibility: Compatible with commercial Raman microscope systems, including Renishaw (inVia Qontor), HORIBA (LabRAM HR Evolution, iHR550), and Ocean Optical Instruments (HRS-5A).
• Potentiostat Compatibility: Compatible with commercial three-electrode electrochemical workstations, including CH Instruments (CHI660E, CHI760E, CHI1140C), Bio- Logic (VMP3), and Corrtest Instruments (CS350M).

Published Application Example

Two-Chamber In Situ Raman Monitoring of Methane Electrooxidation: The cell used in this study, supplied by Beyond Battery® under product code EC-RM2, a two-chamber cell separated by a Fuma bipolar membrane, was coupled with a LabRAM Soleil microscope to study CH₄ electrooxidation over NiCo hydroxides on carbon cloth. Using 532 nm excitation, in situ Raman tracked potential-dependent catalyst evolution, oxygen-vacancy-related changes, and CO intermediates associated with CH₃COOH formation.
