Poroshell 120 is made with a superficially porous particle that has a solid silica core and a porous outer layer. This particle provides high efficiency at lower pressures and is ideal for fast or high-resolution separations of many types of analytes.

• Exhaustive endcapping ideal for use with basic compounds, for those producing poor peak shapes on other columns
• Ideal for peptide mapping with LC/MS compatible mobile phases

The EC-C18 bonded phase is made by first chemically bonding a dense monolayer of dimethyl-n-octadecyl silane stationary phase to the porous shell of the Poroshell 120 silica support. The bonded phase packing is then endcapped using proprietary reagents and procedures to obtain maximum deactivtion of the silica surface.
