PolyRP
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.
