TLC Plates, SIL G-25 UV 254+366, 10x20cm

SIL G unmodified standard silica layers

Technical characteristics

  • Silica 60, mean pore size 60Å specific surface (BET) ~ 500m2/g, specific pore volume 0.75mL/g, particle size 5-17µm

  • 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

  • Indicators: manganese activated zinc silicate with green luorescence for short-wave UV (254nm); special inorganic luorescent pigment with blue luorescence for long-wave UV (366nm)

  • 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
