ZORBAX 80Å StableBondcolumn
1、 When separated under low pH conditions (as low as pH 1), it has the longest column lifespan and the best reproducibility; The stable chromatographic column chemistry allows for use under high temperature and low pH conditions without degradation; Six different bonded stationary phases provide a wide range of selectivity - SB-C18, SB-C8, SB-CN, SB Phenyl, SB-C3, and SB Aq; High purity (B-type) silica gel can achieve good peak shape;
2、 The Agilent ZORBAX StableBond chromatographic column uses a unique, single functional silane with large diisobutyl (SB-C18) or diisopropyl (SB-C8, SB-C3, SB phenyl, SB-CN, and SB Aq) side chain groups, which spatially blocks the key siloxane bonds to the silica gel surface to avoid hydrolysis damage under low pH conditions. In order to provide good stability and maximize lifespan and reproducibility under acidic mobile phase conditions, StableBond fillers are not capped. High purity and low acidity silica gel provides excellent peak shapes for acidic, alkaline, and neutral compounds, making StableBond chromatography columns the preferred choice for low pH method development. The ZORBAX StableBond chromatographic column is compatible with all commonly used mobile phases, including those with high water content.
