Scanning Electron Microscope Imaging Service—JEOL 7900F SEM

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 JEOL 7900F SEM-based scanning electron microscopy Imaging services available to assist customers in biological and materials research.

Name of the Instrument/Platform

JEOL 7900F SEM

MANUFACTURER:

JEOL

MODEL:

7900F

Introduction

This SEM uses a low to moderate energy (0.01 to 30 keV) electron beam to image a sample in high vacuum with sub-nanometer resolution. The tool also has an available low vacuum mode for imaging of non-conductive specimens, as well as Gentle Beam technology to provide a positive bias to the sample stage to reduce landing energy. Detectors available for imaging include: Through the Lens SE; Everhart-Thornley; Retractable backscatter detector; low-vacuum backscatter. Analytical capabilities are based on the equipped Oxford Ultim Max EDS Detector; Oxford Wave WDS detector; Oxford Symmetry EBSD system.
