Reprospher 100 Biphenyl is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, featuring a biphenyl-bonded stationary phase on high-purity, fully porous silica with a 100 Å pore size. The biphenyl ligand introduces strong π-π interaction capabilities, enabling selective retention and resolution of aromatic compounds, ring systems, and structurally related isomers. In contrast to classical C18 columns, Reprospher 100 Biphenyl offers orthogonal selectivity, improved separation of planar and conjugated analytes, and enhanced differentiation of closely eluting compounds. It is especially valuable in pharmaceutical, environmental, and food analysis where aromatic compound separation is critical.
Reprospher 100 Biphenyl from Dr. Maisch HPLC GmbH delivers advanced reversed-phase performance with distinct aromatic selectivity – ideal for challenging HPLC separations of structurally related and aromatic analytes.
