Highest efficiency and resolution size exclusion separations with Sepax Zenix SEC columns
Utilizing proprietary surface technologies, Zenic SEC phases are made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on high purity and mechanically stabilized silica with the particle size of 3 um. Zenix SEC packings 3 um particle size combined with large pore volume achieve the highest separation efficiency and resolution. The well-controlled surface chemistry results in excellent lot-to-lot reproducibility. Sepax's unique bonding chemistry, coupled with the maximized bonding density, allows Zenix SEC to provide high stability and negligible non-specific interactions. The available pore sizes of Zenix packings are 80, 100, 150 and 300 Å. Typical applications for Zenix SEC columns include separation and analysis of biological molecules and water soluble polymers in aqueous buffers.
