Analytical Size Exclusion:
SRT®, Zenix™, SRT®-C, Zenix™-C, and Nanofilm® are five SEC product lines developed for different protein properties, based on innovative surface coating and particle technologies comprised of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on 3, 5 µm high purity and mechanically stabilized silica. It has high stability at high pH at 8.5 and is fully compatible with organics and volatile buffer for LC/MS application. Made of 3 µm silica particles, Zenix SEC packing is a breakthrough technology for size exclusion chromatography. Combination of 3 µm silica particle size and proprietary surface technology enables Zenix SEC phases achieved highest separation efficiency and resolution for biological molecules and water soluble polymers.
Product Line | SRT® | Zenix™ | SRT®-C | Zenix™-C |
|---|---|---|---|---|
Particle size | 5 µm | 3 µm | 5 µm | 3 µm |
Pore size (Ĺ) | 100, 150, 300, 500, 1000 & 2000 | 80, 100, 150, 300 | 100, 150, 300, 500, 1000 & 2000 | 80, 100, 150, 300 |
Resolution | High | Highest, Short column for faster separation | High | Highest, Short column for faster separation |
Efficiency | High | Doubled from 5µm | High | Doubled from 5µm |
Selectivity | Same for SRT® and Zenix™ | Same for SRT®-C and Zenix™-C | ||
Surface structure | Chemically bonded stand-up monolayer | Chemically bonded lay-down monolayer | ||
Recommended Sample Types | Monoclonal antibodies, proteins, peptides, nucleic acids, oligonucleotides, virus, and water-soluble polymers | "Tough samples" such as hydrophobic proteins like insulin, membrane protein monoclonal antibodies derivatized with polymer branches, e.g. polypeptide, PEG. | ||
