TLC/HPTLC glass plates coated with a partial octadecyl (C18, ODS) modification, wettable with water. Based on silica gel 60. Particle size of analytical plates: 2–10 µm. 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. Normal phase or reversed phase separation modes are possible with eluents from anhydrous solvents to mixtures with high concentrations of water. The relative polarity of the eluent determines the polarity of the layer. Order of polarity – silica > DIOL > NH2 > CN > RP-2 > C18-50 > RP-18 W > C18-100
