CNB-12-EC-RM1
In-situ Raman Spectroelectrochemical Cell (Basic Model) Model: EC-RM1
EC-RM1 In-Situ Raman Spectroelectrochemical Cell
A compact three-electrode spectroelectrochemical cell for operando Raman monitoring of electrochemical interfaces.
Product Overview
The EC-RM1 provides direct Raman access to a plate-type working electrode through a quartz optical window while maintaining three-electrode electrochemical control. Its compact single-chamber design supports both static electrolyte filling and external electrolyte circulation, making it suitable for mechanistic studies in electrocatalysis, battery materials, and electrochemical interface research.

Published Application Example
In-situ Raman Monitoring of Glycerol Electrooxidation
The cell used in this study, supplied by Beyond Battery under product code EC-RM1, was coupled with an HRS-5A Raman spectrometer to investigate an Au₁Cu₁–Ag/AgBr catalyst supported on carbon paper. Its single-compartment, three-electrode configuration enabled time-resolved Raman acquisition directly from the working electrode under an applied potential of 1.43 V. Raman changes near 1060 and 1400 cm⁻¹ were monitored during electrolysis.
Demonstrated EC-RM1 Capabilities
- Simultaneous Raman and electrochemical measurements
- Continuous monitoring under an applied potential
- Compatibility with catalyst-coated carbon paper
