KB005935: Agilent Poroshell 120 Column Specifications and Options
Poroshell 120 StableBond SB-Aq
The Agilent Poroshell 120 SB-Aq column combines the productivity enhancements of superficially porous particle technology with unique SB-Aq selectivity. Poroshell 120 SB-Aq is non-endcapped, for greater alternative selectivity. This proprietary phase is ideal for polar compounds and can be used with 100% water.

Start with 5% methanol or acetonitrile in water as the initial solvent, and 100% methanol or acetonitrile as the final solvent. We recommend adding 0.1% formic acid in both A and B bottles. Poroshell SB-Aq can be used with 100% aqueous. f using LC/MS, we recommend starting with 5 - 10 mM ammonium formate, ammonium acetate, ammonium hydroxide, 0.1% acetic acid or 0.1% formic acid. We recommend against using ammonium bicarbonate.
