NEUROSYIL SILICA HPLC COLUMNS: 200 Å* feature high-purity, unmodified silica designed for normal-phase chromatographic applications requiring larger pore sizes. With a 200 Å pore structure, these columns are ideal for separating larger molecules, including complex natural products and biomolecules, while maintaining excellent resolution and peak symmetry. They provide consistent performance, high loading capacity, and are well-suited for pharmaceutical, chemical, and preparative-scale applications where enhanced diffusion and surface access are critical.
