NEUROSYIL Diol HPLC Columns: 100 Å* are designed with a diol-bonded stationary phase on high-purity silica, ideal for separating polar compounds and biomolecules. The 100 Å pore size is optimized for small to medium-sized molecules, offering excellent retention, minimal silanol activity, and sharp peak shapes. These columns support multiple chromatographic modes including normal-phase, reversed-phase, and HILIC, making them highly versatile for pharmaceutical, biochemical, and food analysis applications.
