Sepax Zenix-C SEC Columns
DescriptionPackingCharacteristicsApplicationOrder InfoDownloads
Zenix™-C SEC phase, developed based on innovative surface coating technology, comprises of uniform, hydrophilic, and neutral nanometer thick film chemically bonded to high purity and mechanically stabilized silica. Zenix™-C, uses lay-down monolayer on porous silica as oppose to Zenix of stand-up monolayer (as shown below), offers ideal phase chemistry for hydrophobic samples like insulin, membrane protein monoclonal antibodies derivatized with polymer branches (polypeptide or PEG) separation. The 3µm based packing material allows for high resolution and performance separation.

Stationary Phase Structure Illustration and Comparison

Phase structure difference: a monolayer stands up on the silica surface for SRT® and Zenix™, and a monolayer lays down on the silica surface for SRT®-C and Zenix™-C.
