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.
