are nine 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 Unix™-C, 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.
