Quanta 600 FEG ESEM

An FEI Quanta 600 FEG Mark II Environmental Scanning Electron Microscope achieves 1.5 nm resolution in ESEM mode and can be operated under a range of gaseous environments from 6 x 10-4 Pa to ~1000 Pa. It is equipped with a special wet STEM detector that is ideal for the imaging of nanoparticles in biological systems. This system is our platform for in-situ electron microscopy development with heating and cooling stages allowing imaging from 20-1000C, dual Kleindiek nano-manipulators with a micro-droplet injection system for electrical and mechanical measurements, and gas injection systems for platinum and gold e-beam deposition. The Quanta SEM is equipped with a unique array of accessories to enable the combination of high-resolution imaging and nanoscale manipulation allowing for powerful in-situ experiments involving controlled stimuli and correlated response. In-situ capabilities include: nanoscale manipulation of specimen or probe, access to the large sample volume by fluids, gases, electrical, optical and mechanical probes; detection of sample response to such probes, including the electron beam itself; and the temperature dependences of all these phenomena.
