Features
Base material:
- nano 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 2–8
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 > C18-50 > RP-18 W > C18-100
Available as glass plate with fluorescent indicator.
Layer can be wetted equally well with pure water as with 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.
