Scanning Electron Microscopy (SEM)

Scanning electron microscopy (SEM) is an advanced analytical technique that uses a scanning electron microscope to examine a sample’s surface in exceptional detail at the micro- and nanoscale. SEM is a fundamental tool for modern researchers. It is instrumental during quality control and process control. The analysis provides researchers with crucial insights into a wide variety of material characteristics. Physical and chemical characterisation of materials and substances through image analysis is vital in industries ranging from semiconductor development to drug delivery systems. We perform high-quality scanning electron microscopy tests for scientists working in pharmaceutical science, materials science, biotechnology, biochemistry and gemology. Our analysis can provide crucial information on the surface topography and composition of a sample. Our tests are ideal for scientists working with nanoparticles, microparticles, materials science, polymers, or in general with fundamental materials research.

Technical details

We use a Phenom ProX SEM by Thermo Fisher to perform a variety of scanning electron microscopy analyses. The system specifications are:
  • Magnification range 80-100,000x
  • Resolution ≤17 nm
  • EDS integrated system (energy-dispersive X-ray spectroscopy)
  • High vacuum mode
  • Acceleration voltages: Default: 5 kV, 10 kV and 15 kV
