Electron Microscopy

Within our Image and Analysis Unit labs at The University of Brighton are housed state-of-the-art scanning electron microscopes (SEM).
These are used for research, teaching, and consultancy.
To access our SEM consultancy services please contact us for details.

Zeiss SIGMA FEG-SEM Scanning Electron Microscope (FEG-SEM)
Our SIGMA FEG-SEM delivers high performance nanometre scale resolution digital imaging of samples at up to 1 million times magnification. The FEG-SEM provides SEM imaging with secondary and back scattered electron detectors for large samples, as well as scanning transmission electron microscopy (STEM) imaging of ultra thin sections of, for example, histology sections and nanomaterials. The FEG-SEM is equipped with an Oxford Instruments 80mm² X-Max energy dispersive X-ray analysis system (EDS) for high precision elemental analysis of samples, and a Quorum PP3000T Cryo-SEM system for handling hydrated or liquid samples. A Quorum Q150T turbo molecular-pumped sputter coating system provides the ability to apply a nanometre thin conductive coating to samples if required.

Zeiss EVO LS-15 Environmental Scanning Electron Microscope (ESEM)
Our EVO LS-15 ESEM delivers high performance SEM imaging of hydrated, pressure sensitive, and beam sensitive samples via an environmental ESEM chamber equipped with extended pressure, water vapour injection, and cold stage technologies. These allow secondary and back scattered electron digital imaging and examination of hydrated and biological samples in their native state without the need for further sample preparation. The ESEM is equipped with an Oxford Instruments 80mm² X-Max energy dispersive X-ray analysis system (EDS) for high precision elemental analysis of samples.
