Ultra high resolution (cryo-) SEM


Scanning Electron Microscopy (SEM) has many applications across a multitude of industry sectors. It produces extremely high magnification images (up to 1.000.000x) with sub-nanometer resolution. This SEM produces extreme-high-resolution 3-dimensional images of topography and morphology. Combined with energy-dispersive X-ray spectroscopy (EDX) it can generate localised chemical information. The cryo-setup enables to image fully hydrated samples with this technology. Therefore, the CAT-AgroFood SEM is a powerful and flexible tool for studying a very broad range of materials and products.

Wageningen Electron Microscopy Center

The Scanning Electron Microscope and sample preparation facilities are embedded in the Wageningen Electron Microscopy Center (WEMC). WEMC provides technical support, training and consultation in the area of electron microscopy and elemental analysis. CAT-AgroFood and WEMC jointly provide access to advanced electron microscopes and relevant expertise for biological, food and non-biological science research. In addition to UHR-(cryo-)SEM, HR-(cryo-)Transmission Electron Microscopy (TEM) and routine TEM are available as well.
