As we use sieve analysis for the particle size distribution of any spherical particles. For Non-spherical (i.e. cylindrical shape) particle, what are the standard methods for particle size distribution?
And a couple on sieves:

You may ask our RG colleague Dr. Alan F Rawle ,
among other areas he is specialist in particle size analysis and he is open for scientific assistance and discussions.....
See for example:

Good luck
Estimating the particle size distribution with doing just calculations will result in some errors. Best way to do that, you use DLS for size distribution as well as TEM images for shape distribution and also to compare size distribution from TEM with DLS results. For me I don't trust calculations because the error factor here will be high especially for nanoparticles with different shapes.
Thanks to @Gerhard Martens and his confidence that I can answer the inquiry!
All particle sizing techniques tend to work with equivalents (circular or spherical) because for 3D particles there isn't a single parameter to describe size as you could with computer aided design (CAD). Manufacturing and QA will need a single parameter or number to control a process - not 300 as CAD may provide. So things like size based on equivalent mass or volume become important. Another corollary is that some form of imaging is essential for irregular objects (and imaging/microscopy only provides a 2D representation of a 3D sample).
Take a look at the attachment and come back with any questions. And there's a webinar to support the application note:
