Investigating fully hydrated samples using ESEM Technology
Environmental Scanning Electron Microscopy (ESEM) technology expands the boundaries of traditional scanning electron microscopy to deliver deeper insights into all types of samples. ESEM allows imaging of samples with minimal preparation and adds variables such as hydration, thermal cycling, and introduction of gas to characterize in situ dynamic changes. Using water vapor and a temperature control stage, some of the “impossible to image samples” such as dirty (highly outgassing) and naturally hydrated samples whose properties will change with drying, are easily characterized. With full control of sample hydration, materials and life scientists are able to observe real time material interactions in solution, how humidity changes a sample, and how water interacts at the surface of samples. This moves research possibilities from pure static points in time to dynamic or in situ experimentation.
