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 phasees provide broad selectivity—SB-C18, SB-C8, SB-CN, SB-Phenyl, SB-C3 and SB-Aq
High purity (Type B) silica for good peak shape
Agilent ZORBAX StableBond columns use patented, unique, nonfunctional silanes with bulky disobutyl (SB-C18) or disopropyl (SB-C8, SB-C3, SB-Phenyl, SB-CN, and SB-Aq) side chain groups that sterically protect the key siloxane bond to the silica surface from hydrolytic attack at low pH. StableBond packing materials are not endcapped in order to provide exceptional stability and to maximize lifetime and reproducibility under acidic mobile phase conditions.
