RP-18 W/UV254 octadecyl-modified nano silica layers for HPTLC
ALUGRAM®
Base material: Nano-K silica 60, specific surface (BET) ~500 m²/g, mean pore size 60 Å, specific pore volume 0.75 ml/g, particle size 2 to 10 µm; for preparative plates (1 mm thickness of layer) standard silica 60, particle size 5 to 17 µm, pH stability 2 to 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; partial octadecyl modification, wettable with water, carbon content 14 %. 18-100 normal phase or reversed phase separation modes with eluents from anhydrous solvents to mixtures with high concentrations of water (see figure); the relative polarity of the eluent determines the polarity of the layer.
Recommended application: aminophenols, barbiturates, preservatives, nucleobases, polycyclic aromatic hydrocarbons, steroids, tetracyclines, plasticizers (phthalates).
Available as glass plates with or without fluorescent indicator (UV 254).
Glass plates available on request.
