Working Principle

The XAFS-2 combines electrochemical control with X-ray absorption spectroscopy. A potential or current is applied to the electrodes to drive the reaction, while synchrotron X-rays interact with the target element through the Kapton film window.

The resulting X-ray absorption spectra provide information about the target element's oxidation state, local coordination environment, and electronic structure as the reaction proceeds. The H-type membrane separates the cathode and anode compartments, while gas inlet and outlet connections support experiments under selected atmospheric conditions.

Technical Parameters

Note: Dimensions, membrane material, electrode specifications, allowable pressure, gas flow limits, and optical-window dimensions should be confirmed for the selected configuration.
