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 end capped. Recommended application: compounds, which are too strongly retained on C18 or C8 e. g. , analgesics from blood.
