Preparative Columns: CYANO 200 Å* are engineered for the purification of larger polar and moderately non-polar compounds in both normal-phase and reversed-phase HPLC modes. Featuring a cyano (CN) bonded stationary phase and a 200 Å pore size, these columns provide enhanced surface accessibility and efficient mass transfer for semi-large molecules. They ensure high resolution, reproducibility, and excellent sample loading capacity, making them ideal for preparative-scale applications in pharmaceutical and biochemical industries.
