Preparative Columns: CYANO 100 Å* are high-performance HPLC columns designed for large-scale purification of moderately polar compounds. Featuring a cyano (CN) bonded phase and a 100 Å pore size, these columns offer balanced polarity for both normal-phase and reversed-phase applications. They provide excellent resolution, fast equilibration, and high sample loading capacity—making them ideal for preparative chromatography in pharmaceutical, chemical, and environmental labs.
