Quattro ESEM for Materials Science

Ultra-versatile high-resolution SEM with unique environmental capability.

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:


  • 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)

Dynamic in situ experiments

Quattro’s versatility makes it well-suited to broad range of topics in materials science. It is equally adept at performing conventional high-resolution SEM imaging/analysis and dynamic in situ experiments. It allows researchers to study the widest range of samples in their natural state for the most accurate information about structure and composition.

Unique Environmental Mode

Quattro’s environmental SEM (ESEM) capability allows scientists to study materials in a range of conditions, such as wet/humid, hot, or reactive environments, as they develop new materials and products for a myriad of disciplines, including construction, automotive, packaging, coatings and energy. Quattro’s unique ability to study the progress of chemical reactions, such as oxidation, corrosion, etching, crystal growth, and catalysis, can have a big impact on science and the environment.
