NEUROSYIL Cyano HPLC Columns: 200 Å are engineered with a cyano (CN) functional group bonded to high-purity silica and optimized for the separation of moderately polar compounds. The 200 Å pore size makes them suitable for larger molecules, providing enhanced mass transfer and improved peak resolution. These columns support both normal-phase and reversed-phase applications, offering excellent versatility, fast equilibration, and reproducibility for pharmaceutical, biochemical, and environmental analyses.
