The core shell technology of Poroshell improves separation efficiency and decreases analysis times on standard HPLC equipment. The pore size is smaller in comparison to totally porous silica leading to reduced mass transfer effects meaning that separation happens faster.
By its nature this type of particle has a very narrow particle size distribution.
The diffusion path lengths of all molecules through the column become more uniform - leading to very efficient peaks.
As the particle size is 2.7 μm and because less mobile phase is required to fill the column- the back pressure is only 40-50% compared to <2 μm particle columns.
