Hai Everyone,

I am now studying PhD in the final year and one of my research project is about syntheis of zeolite and zeolite nanoparticle. I have a lot of their images from SEM (mikro size) and TEM (nano size). I want to analyse their particle size.

My zeolites are in aggrerates or in clusters form. Honestly, It is making me grazy. I can not measure their particle size and also their particle size distribution.

I realy need your help. Because I am a beginner, please tel me the prosedur how to analyse them step by step.

Any help is hugely appreciated.

Cheers,
NZN
