Values

  •     •   To serve the needs of the researchers within VISTAS, other academic institutions and industrial partners with utmost sincerity and dedication.
  •     •   Work in an ambience of transparency, with the commitment of maintaining the confidentiality of the work of the users/researchers.
  •     •   Periodical review of all measurements conducted, to impart actionable insights so as to value to the efforts of the researchers.

(a) Field Emission Scanning Electron Microscopy (Quattro ESEM)

Ultra-high resolution scanning electron microscopy with unique environmental capability coupled with materials spectroscopy tools. The Quattro environmental scanning electron microscopy (ESEM) represents the latest development in Thermo Fischer’s SEM technology, comprising of various analytical accessories including energy dispersive X-ray spectroscopy (EDS) with a unique environmental mode. While the Quattro’s field emission gun (FFG) ensures excellent resolution, the adjustment in the vacuum condition provide flexibility to accommodate the widest range of samples in their natural state. Thus the unique environmental mode (ESEM) allows scientists to study materials in a range of conditions, such as wet/humid, and/or reactive environments.
