Manufacturer and model:
Environmental Scanning Electron Microscope Quanta 200 (ThermoFisher, former FEI)
General Information:
An analytical Quanta 200 Environmental Scanning Electron Microscope (ESEM) combines high vacuum, low vacuum and wet-mode to support a variety of material characterization applications. The instrument allows for examination of non-conducting, contaminated, hydrated and even living samples without significant sample preparation.
Key Features:
ESEM Quanta uses Tungsten electron source and allows imaging under wide range of accelerating voltages from 200 V to 30 kV and chamber pressures. The microscope has a complete set of detectors providing imagining in secondary and back-scattered electrons in all the operating modes (high and low vacuum and ESEM mode) at the resolution of 3.5 nm.
The system also includes energy dispersive spectroscopy (EDS) with EDAX detector operated under Genesis 3.5 for elemental analysis with spectral resolution better than 132 eV and chemical imaging.
Chamber pressure could be changed from 6x10-6 Torr up to 15 Torr by using a water vapor. A Peltier cooling stage could be used for moist samples observation.
GATAN C1001 stage could be used for observations down to the liquid Nitrogen temperature.
Start of Operation Date:
November 2002
