Scanning Electron Microscope (SEM) with Energy Dispersive X-Ray Analysis (EDX)

SEM provides superb visualisation at high magnification and the associated EDX analysis capability can provide an elemental profile of a specimen.

SEM-EDX is used in every scientific field and has a wide range of applications across biology, chemistry, forensic science and engineering. Capable of excellent resolution at nanometre scale and with superb depth-of-field, the production of images for investigation and publication is unrivalled. The inclusion of the EDX analysis to investigate chemical composition is particularly useful for engineering and forensic science applications.

 

Our researchers, students and customers have used this facility for:

  • Determination of pollution particulate levels
  • Imaging of diatoms, insects, plant material
  • Bacteria and biofilms
  • Forensic investigation of heat damage to hair
  • Identification and classification of fibres
  • Investigation of microplastics
  • Measurement of tool marks in bone
  • Gunshot residue and firearms research
  • Investigation trace evidence on features (wildlife crime)
  • Quality assessment of photovoltaic thin film fabrication
  • Assessment of manufacturing specifications of abrasive papers
  • Investigation of parts failure in engines and other mechanical structures
  • Determination of effectiveness of engineering processes
  • Investigation of dust deposits in the workplace
