Scanning Electron Microscopy

Scanning electron microscopy offers comprehensive imaging as well as chemical analysis options for just about every type of sample. Enlargements of up to 30,000 fold can be achieved. In addition to metallic samples other materials (excluding liquids) can be examined directly in a scanning electron microscope. Low-pressure technology even allows non-conductive samples to be tested without pre-treatment. This is why this method is also of greatest interest for the field of moulding materials. Furthermore, there are hardly any restrictions as to sample geometry. Samples of up to 20 cm length can be tested without any preparation. Thanks to coupled micro-analytical EDX/WDX tests the chemical composition of the materials can be determined right away in spatial resolution. Automated analyses permit tests across a wide area of the sample without a loss in resolution. Furthermore, topographical tests are carried out, for instance, on the surface roughness or edge measurement.

  • Fracture surface test using SEM
  • Analysis of sink holes and blow holes
  • Assessment of worn surfaces
  • Analysis of moulding materials, filters and refractory materials
  • Chemical identification using EDX without preparation (e.g. non-metallic inclusions)
  • Long-term EDX analysis
  • WDX analyses
  • Sample preparation
