Abstract

Carrier particles (A) for chromatography based on microcapsules (MC) with porous walls, are new. Carrier particles (A) for chromatography are made from, or contain, microcapsules (MC) of diameter 5-50 micron; the MC walls comprise a continuous, but hydrophilically selective and porous separation layer (3) less than 500 nm thick, pores in (3) are 50-500 nm wide with mean spacing 3 micron, and the walls additionally have a mechanically rigid structure, representing less than 10% of capsule volume, that is not, or only slightly, swellable in water. An Independent claim is also includes for a method for preparing (A) from conifer exines.
