Polyaromatic compounds | USP® L11 methods | Wide range of particles | Scale up to prep.
The Cogent RP Phenyl Hexyl ™ columns are a phenyl phase with a C6 linkage to the silica. They are used for reversed phase methods that have polyaromatic hydrocarbons, nitro-aromatics, benzene rings or other polar compounds including peptides.
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.
