TEM Lattice plane resolution standard, graphitised carbon, black plane spacing

Graphitised carbon black is a stable and highly reproducible standard and is considered to be a standard resolution test for transmission electron microscopes. Mounted on a 3mm TEM grid.
These graphitised carbon black particles have lattice planes following the contours of the particles. For a good test of the instrument, choose a field of view where the lattice planes run in several different directions.
Lattice spacing 0.34nm.
