Application Note for Leica EM RES102 – Ceramic membrane filters with pore sizes down to a few nanometres must be investigated in cross-section with regard to the structure of the pores. The smallest pores are of special interest. In most cases, conventional grinding methods cannot be used for such problems, as the pore structure would be distorted. This applies in particular to the pores in the nanometre range.
