In-Situ X-ray Absorption Spectroscopy Reaction Cell (XARC) — Single-Cell

Operando electrochemistry for synchrotron XAS

The In-Situ XAS Reaction Cell (XARC) — Single-Cell is a compact electrochemical reactor designed for synchrotron X-ray Absorption Spectroscopy, enabling time-resolved XANES/EXAFS measurements while the electrode is under electrochemical control. During operation, the sample at the working electrode is probed through an X-ray-transparent window, allowing researchers to track oxidation state, local coordination environment, and reaction intermediates under realistic potential and atmosphere conditions.

Design and key features

Built around a chemically resistant PEEK cell body, the reactor supports robust electrochemistry in challenging electrolytes and catalyst environments. Kapton film windows (user-supplied) provide high X-ray transmission while maintaining sealing integrity. Integrated gas ports allow controlled atmospheres for operando studies.

Highlights

• Single-cell architecture for streamlined beamline setup and alignment
• Gas inlet/outlet ports for inert, oxidising, or reducing environments
• Configurable 2-electrode or 3-electrode operation
• Customisable working electrode geometry; reference/counter options can be matched to your system
• Modular build for rapid assembly, disassembly, and cleaning
• Customisable internal volume to suit electrolyte volume and experimental constraints
  
  

Compatibility and typical use cases

This cell interfaces naturally with standard potentiostats/galvanostats for precise potential/current control and can complement other operando platforms (for example, Raman spectroelectrochemistry cells or battery cyclers for correlated electrochemical–structural workflows).

Common applications include electrocatalysis (OER/ORR/CO₂RR), corrosion and passivation studies, transition-metal redox tracking, and catalyst stability investigations.
