Agilent ZORBAX Original Reversed Phase HPLC Columns
Agilent ZORBAX Original reversed phase HPLC 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 or other compounds where silanol activity enhances selectivity. These columns are available with C18, C8, phenyl, cyano, or TMS stationary phases and are used in many established reversed phase methods.
- Five stationary phases including ODS, C8, phenyl, cyano, and TMS for reversed phase methods
- Based on Type A silica with a higher activity level
- Traditional fully porous 5 µm particles
- Guard columns extend the lifetime of analytical columns without diminishing performance
