NEUROSYIL SILICA HPLC COLUMNS: 100 Å* are packed with high-purity, unmodified silica particles optimized for normal-phase chromatography. With a 100 Å pore size, these columns offer excellent surface activity, making them ideal for separating non-polar and moderately polar analytes, including structural isomers and natural products. They deliver sharp peak shapes, high resolution, and consistent performance, making them suitable for pharmaceutical, chemical, and research applications where silica-based separations are required.
