TLC Plates, Nano-SIL-Diol UV, 10x10cm
Nano-SIL DIOL diol-modified HPTLC silica layers Technical characteristics Nano silica 60, mean pore size 60Å, specific surface (BET) ~ 500m2/g,specific pore volume 0.75 mL/g, pH stability 2–8, particle size 2–10μm Indicator: acid-resistant product with a pale blue fluorescence for short-wave UV (254nm), UV-absorbing substances appear as dark-blue to black spots on a light-blue background Modification Aminopropyl modification, carbon content 3.5% Order of polarity: silica > DIOL > NH2 > CN > RP-2 > C18-50 > RP-18 W > C18-100 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
