Cogent HPS™ is a stationary phase (both bonded and non bonded) that is designed for applications that require high purity silica.

Metal content in Cogent HPS™ is extremely low and this produces very good stability and “deactivates” the silica for use with basic analytes. A very smooth and uniform silica surface results for mechanical strength and stability.

Cogent HPS™ is available for HPLC with unmodified silica, C18, C8, Amino, Cyano or Phenyl stationary phases.
