The FEI Quanta 200 scanning electron microscope is a versatile microscope with a tungsten electron source and three modes of operation. High vacuum (HV) mode allows analysis of electrically conducting and non conducting samples (non conducting samples can be analysed after sputter coating) Low Vacuum & ESEM modes allow analyzing biological and insulating samples without coating. This instrument also has EDS facility for chemical characterisation.
