Web this sample preparation guide is meant for those who are approaching scanning electron microscopy for the first time, or are relatively new to it. Ideally, the smallest representative sample size is the one to use. Identifies problems that all specimens present in examining their structure and analysis in the sem. Techniques like mechanical thinning, ion milling, and chemical etching are employed to achieve optimal sample thickness. Without a vacuum, electrons being aimed at the sample would be deflected (knocked off course) when they hit air particles.

Web in general, preparation of specimens for examination by sem requires stabilization of structures as described in basic protocol 1, then dehydration of specimens as described in basic protocol 2, and finally, ensuring adequate conductivity as discussed in basic protocol 3, or their respective alternatives.
