Energy Dispersive X-ray Spectroscopy (EDS or EDX) is an analytical technique used to identify and characterize the elemental composition of sample material.

Description

Energy Dispersive X-ray Spectroscopy (EDS or EDX) is an analytical technique used to identify and characterize the elemental composition of sample material. It relies on an interaction of some source of X-ray excitation and a sample where the atoms within a sample are excited by an electron beam. This beam interacts with the atom, displacing an electron out of its shell to create an electron hole. Another electron from a higher energy level fills this hole in the lower orbital. The number and energy of the X-rays emitted from a specimen can be measured by an energy-dispersive spectrometer. As the energies of the X-rays are characteristic of the difference in energy between the two shells and of the atomic structure of the emitting element, EDS allows the elemental composition of the specimen to be measured.

Model:

Oxford X-Max 20.

Specifications:

  • Large active area analysis with superb analytical resolution (20mm²).
  • High count rates possible using low voltage.
  • Less time required to obtain high count rates.

Applications:

Assess surface characteristics of various types of materials, help identify possible reasons for failure of components, and contribute to the overall assessment of surface chemistry.
