Unmodified HPTLC silica layers for HPTLC with nano silica gel (particle size 2 to 10 μm).

• Specific surface (BET) ~500 m²/g
• Specific pore volume 0.75 ml/g
• Narrow fractionation of silica particles

Binders are stable in almost all organic solvents. The indicatior is manganese that activate zinc silicate with green fluorescence for short-wave UV (254 nm).

Allows sharper separations, shorter developing times and an increased detection sensitivity compared to standard silica gel plates.
