Particle size distribution analysis according to EC recommendations
Particle size analysis with scanning electron microscopy (SEM).
The analysis is done in conformity with the 2022 European Commission recommendation on the definition of nanomaterials (2022/C 229/01).
At least 300 particles are counted. The particle size distribution histogram is reported. The following statistics are also included in the report:
mean and median
10% value of the total particles
% of the particles that are smaller than 500 nm
% of the fraction of small particles that are smaller than 250 nm
Please indicate if you want any other statistics reported.
