Polar to mid-polar cyano (nitrile) modified silica for reversed phase and normal phase chromatography:
Normal phase: with low-polarity
solvents for many compounds, which can also be separated on unmodified
silica, however, due to the rapid equilibration much more suitable for
gradient separations
Reversed phase: with different selectivity than C18, C8 or phenyl modified packings Available pore sizes 100 and 120 ?, available particle sizes 5 μm, 7 μm and 10 μm,
pH stability at 20 °C: 2–8; carbon content 5 % for 100 ? pores, ~ 3 % for 120 A pores Separation mechanism based on π–π interactions, polar interactions and hydrophobic interactions Corresponding NUCLEODUR? phase see NUCLEODUR? CN / CN-RP |
