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.

• Less retentive for non-polar samples
• Exhaustive endcapping ideal for use with basic compounds, for those producing poor peak shapes on other columns
• Ideal for a wide range of applications

The EC-C8 bonded phase is made by first chemically bonding a dense monolayer of dimethyl-n-octyl 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 deactivation of the silica surface.
