TEM sample requirements

High-quality Transmission Electron Microscopy (TEM) results depend on proper sample preparation. Samples must be electron-transparent, typically below 100 nm in thickness, to allow effective imaging and analysis.

Preparation Methods

We offer guidance and support for preparing samples using:

  • Mechanical Thinning and Polishing: For bulk materials.
  • Ion Milling: Produces damage-free thin sections.
  • Focused Ion Beam (FIB): Site-specific preparation for complex structures.
  • Drop-Casting or Grid Mounting: For nanoparticles and soft materials.
