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.

• Provides greater alternative selectivity
• Steric protection of the bonded phase resists degradation
• Ideal for basic, neutral, acidic samples or aggressive low pH mobile phases

The StableBond SB-C18 bonded phase is made by chemically bonding a sterically-protected C18 stationary phase to the porous shell of the Poroshell 120 silica support. The densely covered, sterically protected, diisobutyl-n-octadecylsilane stationary phase is chemically stable and gives long column life at low pH (pH 1 to 2).
