The Hitachi SU8000 is a versatile SEM offering a wide range of imaging and detection capabilities. For a stable operation and an excellent resolution it is operated with a cold field emitter gun. In addition to the good electron optical properties it comes with different detection systems in order to exploit a wide range of contrast formation mechanisms. Due to it´s low-kV mode it is possible to inspect non-conducting samples without the need for applying a conductive coating prior to inspection.
For chemical analysis the SU8000 is equipped with an energy dispersive x-ray spectrometer (EDS or EDX) utilizing local chemical analysis of the sample.
For wet samples and for samples that undergo morphological changes during drying the SU8000 is equipped with a cryo-preparation and –transfer system as well.
