Agilent ZORBAX Rapid Resolution High Definition (RRHD) threaded columns are specially designed for use with ultrahigh performance liquid chromatographs (UHPLCs) such as the Agilent 1290 Infinity LC and can be used up to an operating pressure of 1200 bar. Eclipse Plus Phenyl-Hexyl RRHD threaded columns are specially designed for higher pressure operation (up to 1200 bar) and are packed with a high-performance microparticulate phenyl-hexyl packing for high-speed and high resolution reversed phase HPLC. Eclipse Plus Phenyl-Hexyl columns are designed for superior peak shape with basic compounds and deliver high efficiency and excellent peak shape with all sample types. Eclipse Plus Phenyl-Hexyl packing is made by first chemically bonding a dense monolayer of dimethylphenylhexylsilane stationary phase to a specially prepared and improved ultra-high purity ¡ 99.995% SiO2 ) ZORBAX Rx-SIL porous silica support. This special ZORBAX silica support (Type B) is designed to reduce or eliminate strong adsorption of basic and highly polar compounds. The bondedphase packing is then endcapped using proprietary reagents and procedures to obtain maximum deactivation of the silica surface. Eclipse Plus Phenyl-Hexyl columns can be used for acidic and neutral samples, but are especially suited for separations of basic compounds that produce poor peak shapes on other columns. These columns can be used for a wide range of applications and over a pH range of 2 to 8, accommodating most popular mobile phases.
