Scanning Electron Microscope
- Damage analysis: Fractures, wear and tear, erosion
- Corrosion: Characterization of corrosion products, determination of the extent of the damage, estimate corrosion- and wear and tear damages
- Process control: Particle analysis, deposition analysis, filter analysis
- Material definition: Metals, plastics, coating, wood
- Element analysis: All elements with atomic number larger or equal to 6 (which is carbon), average analysis, point analysis (1µm resolution), element mapping of surfaces and cross sections
- Analysis of micro-structure: Phase determination, characterization of structure

Case 1: Characterization of micro-structure
Electron beam welding is used to join AISI 316 and Inconel 82.
There are visible segregations in the welding and the heat affected area. In the heat affected area the grain structure is clearly visible because of the segregation in the grain borders.
Case 2: Element analysis
The picture below shows particles filtrated from a liquid flow in a process plant. The size and shapes of the particles can be measured and the element compound determinated. The spectras shows what elements are to be found in the particles.
In face-grinded samples, the element composition can also be determined quantitatively (either by weight % or atomic %).
