Puritas 120Å CN

 

Overview

PURITASTM CN phases are bonded with Cyanopropyl Silane using our ultra pure spherical silica gel as base material. Depending on the choice of the eluent, it can both be used under normal and reversed phase mode. Especially, it is useful for polar compounds separation using methanol / water as mobile phase. The phase is also recommended for the separation of compounds having strong pi-pi interactions.

Key Features

  • Most versatile medium polar phase
  • Useful in both normal and reversed phase
  • Useful as a support of special modification
  • Recommended for separation of basic compounds and for compounds having strong pi-pi interactions
