Agilent ZORBAX Eclipse XDB-C8 RRHT Threaded Column is a high-speed reversed-phase HPLC column designed for higher pressure operation (up to 600 bar) and packed with a high-performance microparticulate C8 packing. The column utilizes the eXtra-Dense Bonding (XDB) technology to bond organo-silane ligands to an ultra-pure silica support, and employs double endcapping to protect the support from dissolution in mobile phases of intermediate and higher pH. It is especially useful for the separation of acidic, basic, and other highly polar compounds by reversed-phase liquid chromatography.
The Agilent ZORBAX Eclipse XDB-C8 RRHT threaded columns are engineered for high-pressure operation up to 600 bar. They utilize eXtra-Dense Bonding (XDB) technology with dimethyl-n-octylsilane ligands bonded to ultra-pure Type B silica support to ensure high efficiency and stability. The packing is doubly endcapped to protect the silica surface from dissolution in mobile phases with intermediate and higher pH levels, making it suitable for separating acidic, basic, and highly polar compounds.
