Analytical and Preparative Size Exclusion
are eight SEC product lines developed based on innovative surface coating and particle technologies comprised of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on 1.8 µm, 3 µm, 5 µm, or 10 µm high purity and mechanically stabilized silica.
Utilizing two unique surface coating technologies - stand-up monolayer bonded on porous silica for Unix™, Zenix®, SRT® and SRT®-10; and lay-down monolayer on porous silica for Zenix®-C, SRT®-C, and SRT®-10C, Sepax offers surface chemistry choices based on sample type and sample hydrophobicity in order to achieve high resolution performance separation.
