Base material silica, pore size 60 Å, particle size 45 µm, specific surface 500 m2/g, pH stability 2–8
Butyl phase, not end capped, carbon content 7 %
Slightly more polar than C18 or C8
Due to shorter alkyl chains the silica surface is not completely shielded
وصف
Butyl modified silica phase for SPE, not endcapped. Recommended application: compounds, which are too strongly retained on C18 or C8 e.g., analgetics from blood.
