Mesopores and macropores are formed within the monolithic silica. The column is no longer packed with small particles but consists of a single monolithic piece of high-purity polymeric silica gel. The mesopores form the fine porous structure within the solid silica in exactly the same way that they do within traditional silica particules. It is ...
