SIL G unmodified standard silica layers for TLC, POLYGRAM^®

• Silica 60
• Specific surface (BET) 500 m²/g
• Mean pore size 60 Å
• Specific pore volume 0.75 ml/g
• Standard grade
• Thickness of layer for analytical plates 0.25 mm, for preparative plates 0.5 and 1 mm
• For 2 mm preparative layers a slightly coarser material is used, indicators: manganese activated zinc silicate with green fluorescence for short-wave UV (254 nm)
• Binders: highly polymeric products, which are stable in almost all organic solvents and resistant towards aggressive visualisation reagents
• Available with or without fluorescent indicator (UV 254)
