Eclipse Plus C8 RRHT threaded columns are specially designed for higher pressure operation (up to 600 bar) and are packed with a high-performance 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-octylsilane stationary phase to a specially pre- pared 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 com- pounds. The bonded-phase packing is then doubly end- capped using proprietary reagents and procedures to obtain maximum deactivation of the silica surface. Eclipse Plus C8 columns can be used for acidic and neutral sam- ples, but are especially suited for separations of basic com- pounds 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 popu- lar mobile phases. The uniform, spherical Eclipse Plus C8 particles are based on an improved ZORBAX Rx-SIL support that has a nomi- nal 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 tech
