XAFS

 

EXAFS can be used to analyze the chemical status

 

 X-ray absorption fine structure (XAFS) can be used to investigate the structural status near specific atoms; it can be implemented in material analysis and other applications.

 Two types of XAFS are considered: Extended XAFS (EXAFS) and Near-Edge XAFS (NEXAFS): EXAFS can obtain the radial distribution around specific atoms and provide the types and numbers of atoms.

 It is a powerful tool for the analysis of storage batteries and for the development of catalysts. It is also suited for the analysis of environmental chemicals.
