- Schedule
- Monday to Friday, from 10 a.m. to 2 p.m. and from 4 p.m. to 6 p.m.
High-resolution analytical field emission scanning electron microscope.
-
- High vacuum (HV) work mode which, together with the field emission illumination system, in-lens detectors and the unique charge compensation system, allows high resolution levels at low voltage and on unshaded samples.
- Observation of samples in STEM mode, starting from samples prepared on small-sized grids, and also for transmission electron microscopy.
- EDX microanalysis (129ev and WD 8.5 resolution), qualitative and semi-quantitative: chemical element distribution map and concentration profiles of a chemical element between two points.
-
