Platinum 300 Si is an unbonded, wide-pore (300 Å) silica HPLC column designed for normal-phase and adsorption chromatography of biomolecules. Its active silanol surface provides strong polar interactions, enabling effective separation of peptides, proteins, and other large or polar analytes not well retained on reversed-phase columns.
The wide-pore structure ensures accessibility for high-molecular-weight compounds, while the high-purity silica guarantees sharp peak shapes, reproducibility, and robustness. Platinum 300 Si is particularly suited for pharmaceutical, biochemical, and proteomic laboratories requiring reliable normal-phase biomolecular separations.
Platinum 300 Si combines wide-pore accessibility with strong polar interactions – the dependable choice for laboratories performing normal-phase biomolecular HPLC separations.
