Preparing Cross Sections of Difficult Materials

Great article from Microscopy Today explains tips on getting good cross sectioned samples for SEM analysis.

ABSTRACT: Preparing cross sections of particulates and wires for scanning electron microscopy study without inducing mechanical damage is difficult. Embedding materials in commercially available epoxy before polishing with a broad unfocused ion beam (like CP-8000 Cross Section Ion Mill) is a simple and inexpensive way to produce a cross section with minimal preparation artifacts. A step-wise procedure is provided for embedding and polishing powders, larger particles, and wires.
