ZORBAX Eclipse XDB Column Specifications and Options
 
ZORBAX Eclipse XDB-CN
Agilent ZORBAX Eclipse XDB-CN columns are an excellent choice for normal-phase applications with basic compounds. The eXtra-Dense Bonding and exhaustive endcapping simultaneously deactivate the silica surface from deleterious interactions with samples, and also protect the silica support from dissolution in intermediate and higher pH environments. This column equilibrates more rapidly than ZORBAX Rx-SIL and is used for many of the same normal-phase applications
