Eclipse Plus C8 threaded columns are specially designed for use with ultra-high performance liquid chromatographs (UHPLCs) such as the Agilent 1290 Infinity LC and can be used up to an operating pressure of 1200 bar. They are packed with a high performance 1.8-µm microparticulate C8 packing for high-speed reverse phase HPLC. Eclipse Plus C8 columns are designed for superior peak shape with basic compounds and deliver high efficiency and excellent peak shape with all sample types. Eclipse Plus C8 packing is made by first chemically bonding a dense monolayer of dimethyl-n-octyl silane stationary phase to a specially prepared, 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 bonded-phase packing is then doubly endcapped using proprietary reagents and procedures to obtain maximum deactivation of the silica surface. Eclipse Plus C8 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 over a pH range of 2-8, accommodating most popular mobile phases. The uniform, spherical Eclipse Plus C8 particles are based on an improved ZORBAX Rx-SIL support that has a nominal surface area of 160 m2 /g and a controlled pore size of 95Å. Columns are loaded to a stable, uniform bed density using a proprietary high-pressure slurry-loading technique to give maximum column efficiency
