In-Situ XAS (X-ray Absorption) Electrochemical Cell (Two-Chamber H-Type)

An in-situ electrochemical cell for synchrotron X-ray absorption spectroscopy (XAS: XANES and EXAFS); the oxidation state and coordination environment of the catalyst are followed under electrochemical control.

In the two-chamber H-type body the cathode and anode compartments are separated by a membrane, keeping anode products away from the measured cathode.

The body has gas inlet and outlet ports for different gas atmospheres and gas-tight experiments. Volume can be customised.

Key Features

• PEEK main body
• X-ray window Kapton (polyimide) film – supplied by user
• Gas inlet/outlet
• In the two-chamber H-type body the cathode and anode compartments are separated by a membrane, keeping anode products away from the measured cathode.

Technical Specifications

Compatibility with beamline geometry, detector clearance and stage mounting should be confirmed before use.

Dimensions, channel sizes and volume can be customised on request; please state special requirements in your quotation request.

Applications

• Operando XANES/EXAFS at synchrotron beamlines
• Following catalyst activation and reconstruction
• Oxidation-state tracking in OER, HER and CO₂RR catalysts
