EDS - Energy Dispersive Spectrometry Testing

SGS MSi is a metallurgical expert in SEM/EDS analysis. Our microscopy staff brings 30 years of experience with microscopy and analysis of failure modes and discontinuities.

SEM/EDS Analysis Generator deposits on fibrous paper tissue, as received. Magnification: 100X. EDS Examination EDS spectrum typical of the corrosion products.

Our expertise in Scanning Electron Microscopy provides valuable information for our clients material needs. In conjunction with EDS (energy dispersive spectroscopy) we can provide a semi-quantitative elemental analysis of the material. This EDS analysis method is particularly useful when an inclusion or discontinuity is found in a sample. Our microscopists scan the surface of the material to identify these discontinuities and determine its elemental make-up. These indications can help determine a failure mode or inconsistency of a material.

Energy dispersive spectroscopy is a type of elemental analysis used to characterize the chemical composition of a material while observing it microscopically in our SEM equipment. We can perform EDS on most metallic samples to identify these characteristics.

The following modes of failure and corrosion utilize the EDS method to identify the cause of failure:

  • Fatigue
  • Intergranular Fractures
  • Overload
  • Hydrogen Embrittlement
  • Wear
  • Cavitation
  • Ductile & Brittle Fractures
  • Intergranular Corrosion
  • Microbiological Corrosion
  • Stress Corrosion
  • Crevice Corrosion
  • Galvanic Corrosion
  • Pitting Corrosion
  • Marine Corrosion
  • Erosion

SGS MSi is equipped to successfully help our clients in all metallurgical failure analysis situations.
