BEH (Ethylene Bridged Hybrid) Technology

Ethylene Bridged Hybrid (BEH) particle technology ensures maximum column performance and longer column lifetimes under all chromatographic conditions. The hybrid particle technology offers many advantages over conventional silica-based particles, including the ability to control silanol activity for better reproducibility, peak shape, and efficiency. The BEH particle is created from two high purity monomers: tetraethoxysilane (TEOS) and bis(triethoxysilyl) ethane (BTEE), which results in highly stable, pH resistant, and mechanically strong particles that set the performance standard for method development. BEH particle technology allows for seamless transfer from analytical to preparative separations.
