Agilent ZORBAX StableBond C8 (SB-C8) HPLC columns offer reduced retention of hydrophobic analytes compared to SB- C18 columns. The SB-C8 columns feature unique, nonfunctional silanes with bulky diisopropyl side chain groups that sterically protect the key siloxane bond from hydrolytic attack at low pH. The non-endcapped phase provides excellent stability and reproducibility for low pH and high temperature applications. Manufactured with fully porous silica in 1.8 µm, 3.5 µm, and 5 µm for use with either UHPLC or HPLC applications.
Features
- C8 column compatible with low pH and high temperature applications
- Reduced retention of hydrophobic analytes compared to SB-18
- Excellent stability and peak shape at highly acidic conditions
- Traditional, fully porous particles available in 1.8 µm, 3.5 µm, and 5 µm sizes
- Guards extend the lifetime of analytical columns without diminishing performance
- USP L7 classification
- ZORBAX StableBond also includes SB-C18, SB-C3, SB-Aq, SB-Phenyl, and SB-CN for alternative selectivity
- ZORBAX StableBond C8 chemistry is aligned with Poroshell SB-C8 for easy transfer from fully porous to superficially porous particle columns
