|
 |
base material:
silica 60, specific surface (BET) ~ 500 m2/g, mean pore size 60 Å, specific pore volume 0.75 ml/g,
particle size 2 – 10 μm, pH stability 2 – 10
indicator:
acid-resistant product with a pale blue fluorescence for short-wave UV (254 nm); UV-absorbing substances apppear as dark-blue to black spots on a light-blue background
diol modification, carbon content 5.5%
order of polarity:
silica > DIOL > NH2 > CN > RP-2 > C 18-50 > RP-18 W > C 18-100
available as glass plates or ALUGRAM aluminium sheets
layer can be wetted equally well by pure water as by organic solvents
|
|
recommended application: steroids, pesticides and plant constituents;
for critical separations an alternative to silica, since it is less sensitive to the water content of the environment; leads to more reproducible results compared to silica |
