• Nano silica 60, specific surface (BET) ~500m /g, mean pore size 60 Å, specific pore volume 0.75mL/g,
particle size 2 - 10 µm
• Indicator: manganese activated zinc silicate with green fluorescence for short-wave UV (254 nm)
Hard, water-resistant and wettable layers due to a special binder system
• Narrow fractionation of the silica particles allows sharper separations, shorter developing times, shorter migration
Distances, smaller samples and an increased detection sensitivity compared to DURASIL plates different selectivity
compared to ADAMANT and SIL-Gplates no reversed phase tendency, more polar than Nano-SIL
