Don't skimp before mounting your sample! Five key steps for ten times more accurate analysis results.

Can you just mount your sample after cutting it? Not necessarily! Have you ever, or are you still, skipping pre-treatment steps? You know, proper pre-mounting preparation directly determines the success or failure of subsequent polishing, observation, and even electron microscopy analysis—especially for complex samples. A little carelessness can affect imaging at best, or even mislead conclusions at worst. Today, we'll systematically review the essential pre-mounting considerations.
