ABSTRACT:
A separation column is provided with a photopolymer component which, when irradiated, causes controlled porosity polymerization. A particularly preferred embodiment is wherein the separation medium is retained by a photopolymer frit, which can be reliably and reproducibly generated with controlled porosity.
