Eclipse Plus C18 RRHT threaded columns are specially designed for higher pressure operation (up to 600 bar) and are packed with a high performance microparticulate C18 packing for high-speed reverse phase HPLC. 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 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 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 C18 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 2–9, accommodating most popular mobile phases. The uniform, spherical Eclipse Plus C18 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 t
This document describes the Agilent ZORBAX Eclipse Plus C18 Rapid Resolution HT Threaded Column, a product specifically engineered for higher pressure operation up to 600 bar. The column is packed with high-performance microparticulate C18 packing designed for high-speed reverse phase HPLC separations.
