In the cryo-SEM setting, the sample is visualized in a frozen state. This setting is very useful when the specimen being observed needs visualiztion in its hydrated form. | In the cryo-SEM setting, the sample is visualized in a frozen state (down to -190 °C). This setting is very useful when the specimen being observed needs visualiztion in its hydrated form. It can be imaged by using either the secondary electrons (SE) or backscattered electrons (BSE) detector. | ||
