About Core-Shell Particles

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.

Mass Transfer Equivalent to Fully Porous sub-2 µm Particles

Mass transfer refers to the time it takes for a sample molecule to enter and leave a particle. In general, lower mass transfer time corresponds to less diffusion and sharper peaks. Even though COSMOCORE 2.6C18 has a larger particle diameter than fully porous sub-2 μm particles, the mass transfer characteristics are similar.

Reduced Back Pressure and Faster Analyses

COSMOCORE Columns deliver performance equivalent to sub 2 micron particles at faster flow rate and analysis time while maintaining a lower back pressure. COSMOCORE can also be used in longer column size to gain additional resolution
