HALO® Biphenyl HPLC columns from Advanced Materials Technology combine hydrophobic, aromatic, and polar selectivities for enhanced retention of polar compounds. The bonded, densely endcapped, dimethyl-biphenyl stationary phase provides a stable, reversed phase packing with enchnaced π-π and mild steric interactions due to the two sequential phenyl groups bonded to the base silica. HALO Biphenyl provides alternative selectivity from C18 columns and is especially useful for separating peaks that elute early on C18 and other phenyl phases. Featuring Fused-Core technology in 2 µm, 2.7 µm, and 5 µm for HPLC, UHPLC, and LC-MS small molecule applications.
