Platinum 300 CN is a silica-based HPLC column with a cyano bonded phase on wide-pore (300 Å) silica, designed to provide unique selectivity for peptides, proteins, and polar biomolecules. The moderately polar cyano functionality combines hydrophobic and dipole–dipole interactions, making it a versatile alternative to C18 and C8 phases in biomolecular chromatography.
The wide-pore structure ensures accessibility for larger analytes, while the CN chemistry offers orthogonal selectivity compared to traditional alkyl phases. Platinum 300 CN is particularly suited for pharmaceutical, biochemical, and proteomic laboratories requiring complementary retention mechanisms.
Platinum 300 CN delivers versatile performance by combining wide-pore silica with polar cyano chemistry – the reliable choice for laboratories requiring complementary biomolecular separations.
