NEUROSYIL Cyano HPLC Columns: 300 Å are designed for the separation of large, moderately polar molecules using a cyano (CN) bonded phase. The 300 Å pore size enhances accessibility for high molecular weight compounds, making these columns ideal for biomolecules, peptides, and complex mixtures. Suitable for both normal-phase and reversed-phase chromatography, they offer excellent selectivity, stable retention, and reproducible performance in preparative and analytical-scale applications.
