The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support.
- High-purity silica
- High-density bonding
- Designed for selectivity
Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.
This exceptionally stable C1 phase features our least-retentive reversed-phase hydrocarbon packing.
