Scanning Electron Microscope Imaging Service—Hitachi S-3000N

Scanning Electron Microscopy (SEM) provides high-resolution and high-depth-of-field images of the surface and near the surface of a sample. SEM is one of the most widely used analytical tools as it can quickly provide very detailed images. SEM provides elemental identification of almost the entire periodic table and is also adept at generating detailed images of surface topography. CD BioSciences offers Hitachi S-3000N-based scanning electron microscopy Imaging services available to assist customers in biological and materials research.

Summary

The Hitachi S-3000N is a Variable Pressure SEM with a tungsten electron source. It was installed in 2000. It is capable of imaging specimens at high vacuum and also in a variable pressure range from 1-270 Pa. This allows nonconducting specimens to be imaged without coating with a conductive film.
There is a standard secondary electron detector, for use in high vacuum only, and backscattered and absorbed electron detectors, which can be used in both high vacuum and variable pressure modes. The microscope has an Oxford Inca EDX system with a light element Si(Li) X-ray detector (15 mm WD).

The Scanning Electron Microscopy Laboratory at CD BioSciences offers a wide range of high-end microscopy equipment. More importantly, our expertise and experience are invaluable to the industries and customers we serve. Please do not hesitate to contact us for cooperation or questions.
