Agilent Zorbax reversed-phase bonded phases, based on Rx-SIL, provide the best peak shape and sample resolution as well as the longest lifetimes for the low, mid and high pH regions. The retention of ionisable compounds changes with pH; therefore achieving optimum resolution for complex samples requires establishing methods at any pH from pH 1-12. Several types of bonded phases are required to cover this wide pH range and provide maximum column lifetime.

The ZORBAX columns described below use unique bonding chemistry to increase the lifetime of the bonded phase and the silica support where needed, thereby providing "Resolution that Lasts" at every pH.

Zorbax Bonus-RP - (A triple endcapped polar imbedded phase with a pH range of 2-8. can be used with 100% aqueous mobile phases)
Zorbax Eclipse XDB - (First choice for method development of small molecules. Working pH range of 2-9)
Zorbax Extend-C18 - (Patented double endcapped bidentate bonded phase that can be used up to pH 11.5)
Original Zorbax - (Ideal columns for the separation of isomeric compounds)
Zorbax Rx - (A good low pH alternative to Eclipse XDB and StableBond columns)
Zorbax StableBond - (Stable at low pH and available in a wide range of chemistries. Working pH range of 1-6)
Zorbax StableBond AQ - (Compatible with 100% aqueous mobile phases. Stable at low pH and available in a wide range of chemistries. Working pH range of 1-6)
Zorbax Columns for LC-MS and High Throughput HPLC - (High efficiency columns designed for fast analysis)
Zorbax Preparative HPLC Columns - (Easy to use scale up columns that are available in 5um, 7um and 10um)
Zorbax Columns For Bioanalysis - (300A widepore columns with exceptional stability and lifetime)
