These columns offer a somewhat different selectivity to the Cogent RP Phenyl phase due to the six carbon aliphatic linker (C6) which adds some extra hydrophobic Selectivity to the pi-pi interactions.
Made with world class, high purity silica and a bonding technology that has been worked out over many years, these columns are among the finest, most reliable Phenyl phases available. Exhaustive, double End-Capping minimizes peak tailing,
The Cogent RP Phenyl™ is a work-horse and "go to" column for many laboratories doing GMP or research HPLC and LCMS.
