Porous Sepax PolyRP Columns                      

PolyRP phases are made of 80% cross-linking PS/DVB spherical particles. These highly rigid particles have both non-porous and porous structures with the particle size selection of 1.7, 3, 5, and 10 µm. The phase structure is phenyl functional groups that enable hydrophobic interaction. Compared with silica based reversed phases, PolyRP phases have advantages over applications at extreme pH (1-14) with special selectivity and slightly lower separation efficiency.

• Uniform particles and narrow pore size distribution
• Extremely high chemical stability
• Unsurpassed pH stability (1-14)
• High retentativity
• Unique selectivity
• High mechanical stability
• Suitable for separations of pharmaceuticals, acidic, neutral and basic organic compounds, and organic acids
• Separation of peptides, amino acids, and proteins
