Question

What type of microscope requires a nonmetal sample to be prepared for viewing by coating it with a thin layer of a conductive material?

Answer 1

Scanning electron microscope All non-metals need to be made conductive by covering the sample with a thin layer of conductive material

Answer 2

The answer is a Scanning Electron Microscope

It is important to obtain and prepare proper samples when using SEM. The sample’s size, state, and shape are things that should be considered before the sample preparation. Some samples need to be coated. Most metals require no preparation since they can easily conduct electricity. Non-metals, however, needs to be coated with a thin layer of gold. Gold is the ideal non-metal and works most of the times.
