Quattro E SEM by Thermo Fisher Scientific

The Thermo Scientific™ Quattro ESEM combines all-around performance in imaging and analytics with a unique environmental mode (ESEM™) that allows samples to be studied in their natural state. It is ideal for a wide variety of academic, industrial, and government labs that want the versatility and ease-of-use needed for multiple users of different experience levels and disciplines on a platform that also supports unique in situ experiments. Quattro’s field emission gun (FEG) ensures excellent resolution, while its three vacuum modes (high vacuum, low vacuum, and ESEM) provide the flexibility to accommodate the widest range of samples of any SEM available, including samples that are outgassing or otherwise not vacuum-compatible.

Quattro ESEM applications include:

Nanocharacterization

• Metals and alloys, fractures, welds, polished sections, magnetic and superconducting materials

• Ceramics, composites, plastics

• Films/coatings

• Geological sections, minerals

• Soft materials: polymers, pharmaceuticals, filters, gels, tissues, plant material

• Particles, porous materials, fibers 

Characterization in situ

• Crystallization/phase transformation

• Oxidation, catalysis

• Material growth

• Hydration/dehydration/wetting/contact angle analysis

• Tensile (with heating or cooling)
