Modular Multifunctional In-Situ XRD/XAS/Raman Electrochemical Flow Cell

In-situ electrochemical flow cell for Raman, XRD and XAS analysis

The Modular Multifunctional In-Situ XRD/XAS/Raman Electrochemical Flow Cell is designed for researchers who need to study electrochemical reactions while simultaneously monitoring structural, spectroscopic or interfacial changes. The cell combines controlled three-electrode flow electrochemistry with interchangeable analytical window options, allowing the same compact electrochemical platform to be configured for Raman, XRD or XAS measurements.

This modular approach is useful for laboratories working across electrocatalysis, battery materials, supercapacitors, corrosion, electrodeposition and energy-conversion research, where different characterisation techniques may be required during different stages of a project.

Best suited for

• Operando Raman studies of electrocatalysts, battery materials, supercapacitor electrodes and corrosion interfaces
• Aqueous and selected non-aqueous electrochemical studies requiring optical or X-ray access to the working electrode
• Multi-technique research where the same electrochemical cell body may be adapted for Raman, XRD or XAS measurements
• Flow electrochemistry under potentiostatic or galvanostatic control
• Studies involving porous electrodes, catalyst-coated substrates, thin films, metal foams, carbon-based electrodes or gas-diffusion electrode configurations
• Research laboratories that need a flexible in-situ platform rather than separate dedicated cells for every analytical technique

Principle of operation

During operation, electrolyte enters the reaction cavity through the reference electrode region, contacts the working electrode surface, then passes towards the counter electrode before exiting the cell. This creates a controlled flow path across the active electrode area while supporting electrochemical measurements using a potentiostat or galvanostat.

The working electrode section can be configured in standard contact mode or gas-diffusion contact mode, depending on the experiment. This flexibility makes the cell suitable for a wide range of electrochemical studies, including catalyst testing, battery-interface analysis, supercapacitor research and reaction-mechanism investigations.

Technique and window configuration

Technique	Recommended window	Typical use	Important compatibility point
Raman / optical microscopy / UV–Vis	Quartz or sapphire	Optical monitoring of electrode surfaces, intermediates and interfacial changes	Check objective working distance, laser focus through the window and microscope-stage clearance
XRD	Beryllium window	Operando or in-situ structural analysis of crystalline phases	Check XRD geometry, incident/diffracted beam path, required 2θ range, window aperture and stage clearance
XAS / XAFS	Kapton film	Synchrotron-based oxidation-state and local-structure studies	Check beamline holder geometry, beam size, transmission path and safety requirements

Key features and materials

• Beryllium window option for XRD measurements
• Kapton film option for XAS/XAFS and synchrotron-based absorption studies
• Three-electrode electrochemical configuration with working, reference and counter electrode arrangement
• Controlled electrolyte flow path across the working electrode area
• Standard and gas-diffusion working electrode contact modes
• Chemically resistant PEEK and high-purity titanium construction
• Compact reaction cavity: 15 × 15 × 1.2 mm
• Suitable for coupling with research potentiostats, galvanostats and selected battery cyclers
• Custom configuration available depending on electrode type, electrolyte, window material and instrument geometry

Important XRD compatibility note

The cell body can be configured for XRD by using an appropriate X-ray-transparent window. However, final XRD compatibility depends on the customer’s specific XRD instrument geometry, incident beam angle, diffracted beam path, required 2θ range, beam footprint, window aperture and sample-stage clearance.

For this reason, ScienceGears recommends confirming the XRD instrument model and measurement geometry before finalising the XRD configuration. Raman compatibility is usually more straightforward for microscope-based backscattering measurements, while XRD requires careful consideration of beam access and angular clearance.
