Gatan X-ray Ultramicroscope (XuM) (accessory for the EVO SEM LS25 microscope)
The Gatan XuM utilises the electron beam in an scanning electron microscope to generate X-rays which are projected through a sample and onto an X-ray camera to form an image. This provides non-destructive imaging of the internal structure of suitable samples. The sample can be rotated and re-imaged multiple times to build up a tomographic dataset from which a 3D reconstruction of the sample can be generated. The resolution limit of this technique is ~400 nm.
