COSMOCORE C18 Core Shell UHPLC Columns

About Core-Shell Particles

Schematic diagram

Core-shell particles consist of a nonporous core inside a porous shell. By using these core-shell particles, one can achieve sharper peaks compared to fully porous silica gel particles of the same diameter.

Uniform Particle Size Distribution Compared to 1.7 µm Particles

Compared to fully porous particles, core-shell particles have a more uniform particle diameter therefore, core-shell particles can be packed in the column more uniformly to minimize sample diffusion.
