Quanta SEM for Materials Science

A proven, advanced, flexible platform for a wide range of materials characterization

The Quanta™ SEM is geared toward increasing publishable results from your lab. The Quanta standard Environmental SEM (ESEM™) capability delivers the extra power to handle the samples and applications you thought were impossible in electron microscopy, while aiding in prediction of material performance over time. The Quanta's ESEM provides for in situ, dynamic experiments that offer many possibilities for materials research:

  • Image hydrated samples.
  • Crystallization or phase transformation during humidity or thermal cycling.
  • Particles in suspensions or self-assembly processes.
  • Corrosion in metals.
  • Tensile testing, with heating or cooling if desired.

Versatility that facilitates dynamic in situ experiments

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

  • oxidation/corrosion samples
  • ceramics, composites, plastics
  • films and coatings
  • soft materials: polymers, pharmaceuticals, gels
  • particles, porous materials, fibers

A family of versatile, high-performance instruments

The Quanta family includes:

  • Quanta 250 and Quanta 250 FEG
  • Quanta 650 and Quanta 650 FEG  

Quanta scanning electron microscopes feature three modes (high vacuum, low vacuum, and ESEM) to accommodate the widest range of samples of any SEM system. All Quanta SEM systems can be equipped with analytical systems, such as energy dispersive spectrometer, wavelength dispersive x-ray spectroscopy, and electron backscatter diffraction. In addition, the field emission gun (FEG) systems contain a S/TEM detector for bright-field and dark-field sample imaging. Another variable that changes amongst the SEM systems is the size of the motorized stage (50mm for the Quanta 250 and 150mm for the Quanta 650) and the motorized z-range (25mm and 65mm, respectively). The Quanta 650 and 650 FEG are each designed with a roomy chamber, enabling the analysis and navigation of large specimens.
