Repromer OH-4000 is a hydrophilic methacrylate polymer phase engineered for aqueous size exclusion chromatography and gel permeation chromatography. It is optimized for the molecular weight range below 300,000 Da, making it ideally suited for the separation and characterization of medium to large water-soluble polymers and biomolecules. The highly hydrophilic surface effectively suppresses non-size-based interactions, ensuring accurate molecular weight determination and excellent peak resolution. Combined with the mechanical and chemical stability of the methacrylate backbone, Repromer OH-4000 offers reproducibility and long service life even under demanding analytical conditions.
Repromer OH-4000 provides reliable size-based separation with high reproducibility – the preferred choice for aqueous SEC/GPC applications up to 300,000 Da.
