Correlation between Equivalent Spherical diameter and Equivalent circular diameter

Hi,

I am working on project to meaure particle sizes ( irregular shape) using coulter counter method and microscopy method. I am getting a very high count with microscopy method as comapred to coulter. Is there any parameter that can be shared by both the methods and could give approximately close counts.

Generaly, it is very common to use an offset correlation method. Quantify your count x size using microscopy. Do the same using your Coulter. Run a linear regression between the two results. You could also perform a BET Surface area and Pore Size Distribution Analysis. Coulter can help with that.
