High resolution SEM with field emission gun Quanta 250 FEG (FEI, USA) with three modes of operation: (1) high vacuum (HiVac) – for conductive samples or non-conductive ones coated with conductive thin layers, (2) low vacuum (LoVac) – for non-conductive samples without preparation and (3) environmental (ESEM) – for hydrated or gas-emitted samples.

SEM Quanta 250 FEG is equipped with many various SE and BSE detectors enable imaging of wide variety of samples in every mode of operation, CCD camera in sample chamber and WetSTEM detector for observation of thin foils or suspensions. The Peltier stage makes possible observation of in-situ dynamic experiments in microscopic chamber and EDS spectrometer (EDAX, USA) enables qualitative and quantitative chemical microanalysis of samples studied.
