Restek Ultra Biphenyl 100Å Columns – Enhanced Selectivity for Aromatic Compounds

Restek Ultra Biphenyl 100Å Columns are high-performance HPLC columns designed to provide enhanced selectivity for aromatic, unsaturated, and structurally related compounds. The biphenyl stationary phase offers complementary selectivity to conventional C18 phases, making it an excellent choice for challenging separations and HPLC method development.

Key Specifications: Biphenyl stationary phase, 100 Å pore size, silica-based packing, and availability in various particle sizes and column dimensions to meet different analytical HPLC requirements.

Typical Applications: Ideal for pharmaceutical analysis, environmental testing, food and beverage analysis, and the separation of aromatic or structurally similar compounds. Restek Ultra Biphenyl 100Å Columns are particularly useful when additional π-π interactions can improve analyte retention, selectivity, and chromatographic resolution.

Choose Restek Ultra Biphenyl 100Å Columns for robust, reproducible HPLC separations and alternative selectivity in demanding analytical applications.
