CNB-12-EC-RM2
In-situ Raman Spectroelectrochemical Cell Model: EC-RM2
EC-RM2 In-Situ Raman Spectroelectrochemical Cell
A two-chamber cell with a replaceable ion-exchange membrane for in-situ Raman monitoring of electrochemical interfaces.
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 Observation
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

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.
Demonstrated EC-RM2 Capabilities
- Bipolar-membrane-separated, two-chamber operation
- Simultaneous Raman and electrochemical measurements
- Compatibility with carbon-cloth-supported catalysts
