Summary

This document specifies how to capture, measure and analyse transmission electron microscopy
images to obtain particle size and shape distributions in the nanoscale.
This document broadly is applicable to nano-objects as well as to particles with sizes larger than
100 nm. The exact working range of the method depends on the required uncertainty and on the
performance of the transmission electron microscope. These elements can be evaluated according to
the requirements described in this document.
