GromSil 120 Cyan-1 ST is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, based on fully porous, high-purity silica with a 120 Å pore size and bonded with cyanopropyl (CN) ligands. This polar stationary phase offers weaker hydrophobic retention than C18 or C8 phases, combined with dipole-dipole interaction capability — making it ideal for the separation of moderately polar compounds and structural isomers.
Its unique selectivity and short retention times are especially useful in fast method development, normal-phase compatibility, and orthogonal reversed-phase separations.
With its polar functionality and balanced retention behavior, GromSil 120 Cyan-1 ST from Dr. Maisch HPLC GmbH is a flexible choice for reversed-phase and normal-phase separations of structurally diverse analytes.
