Pur Silica is an unbonded high-purity silica gel chromatographic column, which relies on silica hydroxyl groups for normal phase separation and can also be used in hydrophilic interaction (HILIC) mode. Its separation capability depends on hydrogen bonding, dipole, and electrostatic interactions between the active sites on the silica surface and the analytes, offering unique selectivity for positional isomers, natural products, and fat-soluble vitamins. It is a classic choice for developing normal phase chromatography methods.
