micro-compositional analysis

The HITACHI S-3400N SEM is used for low to medium magnification studies of a variety of specimens; starting from failure analysis to micro-compositional analysis. Samples of all shapes, sizes and types can be examined using the SEM and it the most heavily used microscope in the laboratory. This SEM is in operation at NML from January 2006.
