Agilent ZORBAX StableBond Column Specifications and Options
Agilent ZORBAX SB-CN is densely covered, sterically protected, diisopropyl cyanopropylsilane stationary phase bonded to ZORBAX silica. It is particularly well-suited for use with aggressive mobile phases (e.g. pH <2, high ionic strength, ion-pair additives, etc.) since the steric protection of the bonded phase resists degradation caused by such mobile phases.

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. This column can be used with 100% aqueous. If 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.
