Zorbax 300A Stablebond

• Four different bonded phases for reversed-phase selectivity optimization of peptides and proteins
• Exceptional stability and long lifetime at low pH with TFA containing mobile phases
• Excellent reproducibility
• Available in capillary and nano column dimensions for proteomics and other LC/MS applications

Agilent ZORBAX 300Å StableBond columns are an ideal choice for the reproducible separations of proteins and peptides for two reasons. Wide-pore, 300Å columns are necessary for an efficient separation of proteins and peptides, or other large molecules, in order to allow these analytes to completely access the bonded phase. Second, 300StableBond columns are unmatched in their durability at low pH, such as with TFA-containing mobile phases. For LC/MS separations at low pH, 300StableBond columns can also be used with formic acid and acetic acid mobile phase modifiers.
