Grant support from the National Institutes of Health has made it possible for us to further our microscopy capabilities by adding the Hitachi S-4800 SEM to our list of available equipment. In addition to the NIH grant we would also like to thank Mike Apicella, Chuck Grose, Tim Starner, Michael Welsh and Mary Wilson for helping to make this possible.
This state-of-the-art field emission SEM includes advanced detection technology with a high resolution. Specific features include:
A guaranteed resolution of 2.0 nm at 1kV for low voltage applications.
An objective lens design with "Super ExB Filter" technology. The Super ExB Filter collects and separates the various components of pure SE, compositional SE and BSE electron signals.
A specimen stage for large sample applications with 110mm x 110mm stage movement and computer controlled 5 axes motorization with graphical interface software.

The S-4800 can be found in room 80 of the Eckstein Medical Research Building. To reserve this equipment visit our online scheduler. Questions or comments about this equipment can be sent to Randy Nessler at randy-nessler@uiowa.edu.
