Main Function and Application:

Quanta 200 FEG-ESEM takes the advantage of the high resolution of the field emission electron microscopy and the ability to fit the diversity of samples of the ESEM. It can inspect and analyze the many kinds of samples under stable state and dynamic state. Under the condition of the steam with some pressure, it can analyze the surface appearance and the components of the micro-field so that it can avoid the sample under the condition of the vacuum to lose the water to result in the change of the surface appearance. Special to the nonconductor that needn’t plating the electric film, it can analyze the surface appearance and the components of the micro-field. It can analyze the surface appearance of many kinds of biology, the substance with water and nonconductors etc. widely.
