Zorbax Analytical HPLC Columns from Agilent
From research to routine QA/QC, there is a ZORBAX HPLC column that offers an optimized solution for your specific measurement and purification application.Agilent’s ZORBAX columns are optimized for high throughput analysis with the widest range of Rapid Resolution HD (1.8 µm 1200 bar), Rapid Resolution HT (1.8 µm) and Rapid Resolution (3.5 µm) columns. Zobax columns are available with a huge variety of bonded phases ideal for small molecule separations at analytical scale, offering the broadest range of selectivity and column dimensions.
Highlight of the Product Offering
Zorbax StableBond
ZORBAX 80Å 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 1–6 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.
Zorbax Eclipse XDB
Agilent ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns provide good peak shape over a wide pH range (2–9) for additional method development flexibility with one family of columns. Eclipse XDB columns can be used for method development at low pH (2–3) and the same column can be used for method development in the mid pH (6–8) region.
Zorbax Extend
Agilent Zorbax Extend-C18 columns incorporate a unique patented bidentate silane, combined with a double-endcapping process that protects the silica from dissolution at high pH - up to pH 11.5. Columns are best applied for separations of compounds that are either (1) basic and have little or no retention at low or intermediate pHs, (2) more stable or more soluble at high pH, or (3) basic and show poor peak shape at low or intermediate pH.
Zorbax Original
Agilent Original ZORBAX columns are made with Type A silica and are useful for many applications of acidic or neutral compounds. These columns have a higher activity level and are therefore useful for separating isomers (e.g. cis-trans, geometric) or other compounds where silanol activity enhances selectivity. These columns are used in many established methods
Zorbax Bonus RP
Agilent Zorbax Bonus-RP columns provide unique selectivity and applicability for mid pHs with an embedded amide linkage in the C14-alkyl chain. At pH 7 Bonus-RP provides excellent peak shape for even the most challenging basic compounds. Bonus-RP is protected from hydrolysis at low pH using the same sterically protecting bulky side chains as StableBond, and also is triple endcapped to minimize silanol interactions and improve stability at mid pH. Bonus-RP can be used without phase collapse in 100% aqueous mobile phases.
