Polymer columns

Also: One can imagine that the pore problem can be licked someday?

Hi

I was just checking few polymer based columns and realized that some of them doesn’t mention the pore size..like Water’s YMC-Pack Polymer C18 and Shodex Rspak..?

Why is this so…does this mean that these column are packed with non porous polymer beads??

Thanks
