FEI Quanta 600 FEG

FEI Quanta 600 FEG: Environmental FEG-SEM equipped with EDS, heating stage, mechanical testing fixture

The FEI Quanta 600 FEG is an environmental SEM using a Schottky field emission (FEG) electron source that can operate in high-vacuum, low-vacuum and extended-vacuum modes. It is used to image samples that are difficult to impossible to image in standard high vacuum SEMs; the SEM can operate with pressures around the sample up to 4000 Pa and in conjunction with a Peltier stage can image fully hydrated samples, a critical advantage for imaging biological samples. in situ experiments such as hydrating, dehydrating and heating samples are possible with this ESEM.
