In-Situ Raman Spectroelectrochemical Cell – REC 01

In-Situ Raman Spectroelectrochemical Cell for Real-Time Interface Analysis

The In-Situ Raman Spectroelectrochemical Cell – REC 01 is designed for researchers who need to combine electrochemical control with Raman spectroscopy in a compact and practical experimental platform. It enables real-time observation of molecular and structural changes at or near the electrode surface while an electrochemical reaction is taking place, making it highly valuable for mechanistic studies in electrocatalysis, corrosion, energy storage and functional materials research.

Working Principle and Measurement Approach

REC 01 integrates a spectroscopic optical window with a three-electrode electrochemical configuration so that Raman measurements can be collected during polarisation, cycling or potential-step experiments. The quartz window allows Raman excitation and signal collection while the electrochemical cell maintains the required electrode arrangement for controlled measurements. This arrangement helps researchers correlate spectral changes with current, potential and reaction progress in the same experiment.

Configuration Options

REC 01 is available in two standard configuration options to suit different sample mounting requirements:

With pressing gland design
The standard cell kit includes a Pt wire counter electrode (CE), an Ag/AgCl reference electrode (RE) or other non-aqueous Ag/Ag+ reference electrode, and a glassy carbon working electrode (WE). In this configuration, the glassy carbon can also be used as a current collector to install carbon paper, nickel foam, or other sample materials.

Without pressing gland design
The standard cell kit includes a Pt wire counter electrode (CE), an Ag/AgCl reference electrode (RE) or other non-aqueous Ag/Ag+ reference electrode, and a glassy carbon working electrode or other customised working electrode option.
