jeol 840a @er-c

The JEOL 840A is a medium resolution scanning electron microscope used for conventional microstructure analyses. The instrument is designed for the analysis focusing on the physical and chemical microstructure of solid state materials allowing spatially resolved compositional analysis by an EDAX Genesis 200 X-ray emission spectroscopy system.

Microscopists planning to use this instrument should consult Eva-Maria Würtz or Wilma Sybertz.
