SEM Sample Preparation Series

Proper sample preparation is key for quality scanning electron microscopy imaging. In this video, we demonstrate gold sputter coating, an essential technique to combat electron buildup on samples. By applying a nanometer-thin layer of gold, we can mitigate the charging effect that leads to poor signal-to-noise ratios. Learn how this simple coating procedure can drastically improve your SEM images by reducing noise and artifacts from improper sample prep.
