Which of the following advantages does not apply to scanning electron microscopy?
Correct answer is D Sample preparation for scanning electron microscopes requires highly technical equipment for good results. The sample must be coated with metal, usually by sputtering with gold. The coating must be applied very thinly and evenly to avoid masking or distorting surface features. The sample is kept in a vacuum to avoid deterioration of the coating, and is vacuum-mounted in the electron beam in a complex holder which allows for various image modes and orientations to be used.
