Beijing Scistar EC-FXAS-III, In-An in-situ cell for following operando electrochemical experiments using x-ray absorption in fluorescence mode at HXMA.
Introduction:
Electrochemical operando Cell (EC-FXAS-III) is a unique operando cell for synchrotron radiation X-ray absorption spectroscopy characterization in the electrochemical field. This type operando cell is optimized from the EC-FXAS-II. Compared with type II, this type cell has a better air-tightness design, and equips with the gas inlet and outlet to make the product more comprehensive and complete
Main features:
...
The operando cell is a customized electrochemical cell, which can be applied for X-ray absorption spectrum characterization in fluorescence mode.
