FEI Quanta 650 Scanning Electron Microscope

About

Location: Wilsdorf B003

The Schottky Field Emission SEM microscope is capable of imaging and microanalysis on all specimens, with or without preparation. Characterization of both traditional samples from metals, fractures and polished sections, to non-conductive soft materials. Attachments for elemental analysis with Energy-Dispersive X-ray Spectroscopy (EDS) and for grain orientation mapping with an Electron Back-Scatter Detector (EBSD).  

SEM Technique Summary:

• SEM and Compositional Analysis of Metals, Glasses, Semiconductors, Ceramics, Polymers, Geologic Materials, Catalysts, Pharmaceuticals, etc.
• High vacuum imaging: <0.25 mTorr
• Low-vacuum imaging: 0.25 mTorr to 1.5 Torr
• Environmental SEM (ESEM): 1.5 Torr to 6 Torr
• Secondary Electron (SE) imaging for topographic contrast
• Back-Scattered Electron (BSE) imaging for chemical contrast
• Scanning Transmission Electron Microscopy (STEM) option for imaging of thin samples
• Quantitative Elemental Analysis and Mapping of Materials with EDS
• EDS Elemental Sensitivity:> 0.1 wt.% (weight percentage) for Z > 5 (B)
• Mapping of grain orientations, texture and phase analysis with the EBSD system
• Montage imaging of large samples
• Sample size up to 4 x 15 x 15 cm³ ( H x W x D)
