Product Intelligence: Beyond Light: Characterizing the Molecular World With Scanning Electron Microscopes

A scanning electron microscope, or SEM, employs a focused beam of high-energy electrons to produce signals at the surface of solid specimens. As outlined in this article, purchasing considerations for the laboratory include identifying the type and range of samples to be analyzed and whether an entry-level benchtop SEM is required versus an ultrahigh-resolution system that uses a field-emissions gun (FEG).
