Diol-modified HPTLC silica layers available as glass plate with fluorescent indicator. Recommended for 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.
- Layer can be wetted equally well with pure water as with organic solvents
Base material: Nano silica 60, specific surface (BET) ~ 500 m²/g; specific pore volume 0,75 mL/g; particle size 2 to 10 μm; pH stability 2 to 8.
Modification: Diol, carbon content 5,5%
Indicator: Acid-resistant product with a pale blue fluorescence for short-wave UV (254 nm), and UV-absorbing substances appear as dark-blue to black spots on a light-blue background.
