CommaSil® C18 Universal HPLC Column

CommaSil® C18 HPLC Column is crafted from high-purity silica microspheres, ensuring a high level of homogeneity in particle size and pore structure. The activity of the silica microspheres is effectively mitigated through an advanced surface bonding and comprehensive capping process, rendering the columns suitable for separating analytes with varying hydrophobicity. This versatility positions
