TLC Plates, POLYGRAM SIL G UV254, 5x20cm
SIL G unmodified standard silica layersTechnical characteristics
Silica 60, mean pore size 60Å, specific surface (BET) ~ 500 m2/g, specific pore volume 0.75mL/g, particle size 5-17µm. Indicator: manganese activated zinc silicate with green fluorescence for short-wave UV (254nm) Thickness of layer for analytical plates 0.25mm, for preparative plates 0.5 and 1mm; for 2mm preparative layers a slightly coarser material is used. Binders: highly polymeric products, which are stable in almost all organic solvents and resistant towards aggressive visualization reagents; binder system for POLYGRAM sheets is also completely stable in purely aqueous eluents
