Transmission Electron Microscopy (TEM)
This technique uses a beam of electrons that is transmitted through an ultra thin specimen, interacting with the specimen as it passes through it. The electron density of the various portions of the sample respond differently to the electrons differently leaving an image that is representative of gradient areas of electron density.
Ultra thin specimens are prepared using a microtome or a cryomictrotome on polymer pieces or embedded specimens.
Applications:
- Phase morphology
- Dispersion of polymer blends
- Material selection
- Quality control
- Failure analysis
- Competitive product analysis
- Cellular structure of dispersed phases
- Nanoscale particle incorporation
- Metalized layer coherence and thickness analysis in laminated films
