Features 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 for preparative plates (1 mm thickness of layer) standard silica 60 particle size 5–17 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. Partial octadecyl modification, wettable with water, carbon content 7.5 % Order of polarity: silica > DIOL > NH2 > CN > RP-2 > C18-50 > RP-18 W > C18-100 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).
