NEUROSYIL Amino HPLC Columns: 300 Å are specially engineered for the separation of large polar molecules, oligosaccharides, and biomolecules using normal-phase or HILIC techniques. The 300 Å pore size provides enhanced surface accessibility, ensuring better interaction with high molecular weight compounds. These amino-bonded columns offer high stability, consistent peak shapes, and excellent retention of hydrophilic analytes, making them ideal for advanced analytical and preparative applications in biochemical and pharmaceutical research.
