CONCLUSION
SEM and EDS are effective tools for
visualizing the appearance and compo-
sition of materials in extremely precise
detail. With recent improvements in
silicon drift detectors—even with chal-
lenging samples that are fragile, non-
conducting, or prone to decomposing
when exposed to an electron beam—
analysis can be done safely, quickly, and
in some cases, interactively.
