ZORBAX® 80 Å StableBond columns are made using bulky, patented, unique silanes that sterically protect the siloxane bond. Acid labile endcapping reagents are not used.

• Longest column lifetime and best reproducibility for low pH separations down to pH 1
• Patented stable column chemistry allows use at high temperature and low pH without degradation
• Six different bonded phases provide broad selectivity SB-C18, SB-C8, SB-CN, SB-Phenyl, SB-C3, and SB-Aq
• Different selectivity compared to conventional end-capped chemistries
• High purity (Type B) silica for good peak shape

ZORBAX® 80 Å StableBond columns are made using bulky, patented, unique silanes that sterically protect the siloxane bond. Acid labile endcapping reagents are not used. The result is vastly improved column life and extraordinary chemical and temperature stability in the pH 1 to 6 range for a wide variety of phases (SB-Aq, SB-C3, SB-CN, SB-Phenyl, SB-C8, and SB-C18). Excellent peak shape is expected for many basic compounds because of the ultrapure Rx-SIL support.

StableBond columns are available in 1,8, 3,5, 5 and 7 μm particle sizes for high speed, high resolution, analytical and prep scale separations.
