In reversed phase mode, cyano (nitrile) phases are the most polar and least retentive of all reversed phase packings. Extremely hydrophobic compounds, which do not elute on standard C18 and C8 packings with typical reversed phase eluents, can be separated using cyano phases. Both reversed and normal phase separations can be carried out on this material.
