PolyRP columns from Sepax are columns based on polystyrene-divinylbenzene resin (PS/DVB) for reverse phase chromatography. This phase has a functional phenyl group on its surface, which enables hydrophobic interactions. Compared to silica phases, the PolyRP columns exhibit extreme pH stability in the range of 1.0-14. The columns are available with porous and non-porous spherical particles.
Phase | Modification | Particle size | Pore size | Surface area | pH range |
PolyRP | Phenyl | 5, 10 µm | 100, 300, 500, 1000 Å | 280 m²/g for 100 Å | 1.0 - 14.0 |
PolyRP-NP | Phenyl | 1.7, 3, 5, 10 µm | Non-porous | N/A | 1.0 - 14.0 |
