NEUROSYIL PFP HPLC Columns: 100 Å* utilize a pentafluorophenyl (PFP) bonded phase on high-purity silica with a 100 Å pore size, offering unique selectivity through π–π interactions, dipole–dipole forces, and hydrogen bonding. These columns are ideal for separating aromatic compounds, halogenated substances, isomers, and polar analytes that are challenging to resolve on traditional C18 phases. With excellent peak shape, high reproducibility, and versatile reversed-phase compatibility, they are well-suited for pharmaceutical, environmental, and analytical chemistry applications.
