Restek Pinnacle DB Biphenyl 140Å Columns – Enhanced Selectivity for Aromatic Compounds

Restek Pinnacle DB Biphenyl 140Å Columns are high-performance reversed-phase HPLC columns designed to deliver enhanced selectivity for aromatic, unsaturated, and structurally related compounds. The biphenyl stationary phase provides distinctive π-π and hydrophobic interactions, offering complementary selectivity to conventional C18 phases and excellent performance for challenging chromatographic separations.

Key Specifications: Biphenyl stationary phase, 140 Å pore size, silica-based packing, and optimized surface chemistry for reliable retention, good peak shape, and reproducible HPLC performance. The 140 Å pore structure supports efficient analyte access to the stationary phase.

Typical Applications: Ideal for pharmaceutical analysis, environmental testing, food and beverage analysis, chemical analysis, and quality control. Restek Pinnacle DB Biphenyl 140Å Columns are particularly suitable for aromatic compounds, structurally similar analytes, and complex mixtures where enhanced selectivity and chromatographic resolution are required.

Choose Restek Pinnacle DB Biphenyl 140Å Columns for robust, reproducible HPLC separations and alternative selectivity in demanding analytical applications.
