The columns have an inner solid silica impermeable core that is surrounded by an outer porous layer of silica which forms the outer shell. A big difference between fully porous and core-shell ...

The particles in the columns are not fully porous but instead have a solid silica core surrounded by a porous outer layer. The very tight particle size distribution results in columns with high ...

The evolution of porous particle technology—including the development of core–shell and superficially porous particles—has significantly enhanced separation efficiency and reduced analysis time.
