SGS analyzes, identifies, and characterizes unknown residues, filter debris, contaminants, particles, and other samples with scanning electron microscopy (SEM). Lubricants, fluids, greases and other materials are analyzed for particles, wear metals, unknowns identification and other needs by using Scanning Electron Microscopy (Energy Dispersive SEM/EDS). SEM is an excellent technique for failure analysis and root cause analysis.

Impurities contaminents

Scanning Electron Microscopy assists in failure analysis investigations, wear metal investigations, and related issues. 

SGS SEM/EDS Capabilities include:

  • Unknown Residue and Contamination Identification
  • Filter Debris Analysis
  • Elemental Composition
  • Particle Characterization:
    • Particle Size Distribution
    • Particle Chemical Makeup

SEM analysis provides quantitative, compositional measurements. The SGS SEM instrument measures the size and shape of wear debris particles, and determines the elemental composition of the particles analyzed.

 The scanning electron microscope is located at one of our premier oil condition laboratories (legacy Herguth) in Vallejo, California. SEM testing is conducted by seasoned veterans who understand the techniques required for the analysis of particles, wear metals, and other materials. Wear particle analysis helps our customers understand issues and problems with equipment and lubricating oils, greases, and other fluids and materials.

 Shipping samples to the SGS SEM lab is easy to arrange, contact SGS for more information.
