In-Situ Raman Spectroelectrochemical Cell (Two-Chamber, Replaceable Membrane)

In this two-chamber in-situ Raman cell the cathode and anode compartments are separated by an ion-exchange membrane, so products formed at the anode do not disturb the measurement at the cathode.

The reference electrode sits in the same compartment as the working electrode, which reduces iR drop (the potential error caused by solution resistance).

The ion-exchange membrane is supplied by the user and is easily replaced thanks to the screw-clamped joint.

Key Features

• Two compartments separated by a membrane, screw-sealed joint
• Ø37 mm quartz window, electrode–window distance < 6 mm (manufacturer data)
• Reference and working electrodes in the same compartment: low iR drop
• The cell can be connected to a pump for continuous electrolyte flow or filled with a syringe for static measurements.
• Supplied as standard with an Ag/AgCl reference electrode and a graphite rod counter electrode; an Ag/Ag⁺ reference and Pt wire counter electrode can be chosen at no extra cost.

Technical Specifications

Applications

• CO₂RR, NRR and organic electrosynthesis where anode products must be kept apart
• Tracking intermediates during methane and alcohol electro-oxidation
• Raman study of catalyst reconstruction in a two-compartment set-up
