Energy Dispersive X-ray Spectroscopy (EDX)

Energy dispersive X-ray analysis (EDX) is a microanalysis technique used in conjunction with Scanning Electron Microscopy (SEM). EDX offers elemental identification and quantitative compositional information of features down to ~1 µm in size. EDX can be performed as point or area analysis, line scans and mappings.

Typical applications:

  • Chemical analysis of thicker deposits, coatings and oxides
  • Corrosion evaluation
  • Identification of metallic materials
