SMT AquSep is unique reversed phase packing material designed to have both hydrophobic and truly hydrophilic spacer ligands. The mixed-phase consists of a meticulously controlled mixture of hydrophobic, C18 molecules, and proprietary hydrophilic molecules, chemically attached on the silica substrate, using Total Coverage technology.
The result is a stationary phase that has all of the following characteristics:
- Stronger retention of polar molecules in aqueous eluent
- Reduced back-pressure; the hydrophilic hybrid enhances the solvation of the bonded phase in an aqueous environment
- Different selectivity compared to conventional C18
- Eliminates the need for ion pairing reagents
