The FEI Quanta 400 FEG Scanning Electron Microscope (SEM) is a versatile high performance instrument equipped with a field emission gun and nominal resolution of <2 nm. It can be operated in high-vacuum, low-vacuum and ESEM modes and accommodates a wide range of samples. In addition to secondary electron mode (SEM), the instrument is equipped with a backscatter electron detector, a Peltier cold stage, and an PGT thin-window energy-dispersive X-ray spectrometer capable of analyzing elements down to C. The SEM is also equipped with an HKL electron backscatter diffraction detector for crystal structure identification and orientation mapping, and a Gatan Chroma-CLII cathodoluminescence detector for live color rendering.

No coating needed, can image moist materials, microbes survive study under the beam. NSF funded
