Unmodified HPTLC silica layersNano silica 60, specific surface (BET) ~ 500 m2/g, mean pore size 60 Å, specific pore volume 0.75 mL/g, particle size 2–10 µmIndicator: manganese activated zinc silicate with green fluorescence for short-wave UV (254 nm)Binder: highly polymeric product, which is stable in almost all organic solvents and resistant towards aggressive visualization reagentsNarrow fractionation of the silica particles allows sharper separations, shorter developing times, shorter migration distances, smaller samples and an increased detection sensitivity compared to SIL G plates
