Eclipse Plus C18 columns are designed for superior peak shape with basic compounds and deliver high efficiency and excellent peak shape with all sample types. Eclipse Plus C18 is especially useful for the separation of acidic, basic, and other highly polar compounds by reverse-phase liquid chromatography. Eclipse Plus C18 packing is made by first chemically bonding a dense monolayer of dimethyl-n-octadecylsilane stationary phase to a specially prepared, an improved ultra-high purity (>99.995% SiO2), ZORBAX Rx-SIL porous silica support. This special silica support (Type B) is designed to reduce or eliminate strong adsorption of basic and highly polar compounds. The bonded-phase packing is then doubly endcapped using proprietary reagents and procedures to obtain maximum deactivation of the silica surface. Eclipse Plus C18 columns can be used for acidic and neutral samples, but are especially suited for separating 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 2-9, accommodating most popular mobile phases
