TLC and HPTLC Plates Manufactured by Macherey-Nagel GmbH & Co., Germany
Layers for special TLC separations
SIL N-HR
SIL G-25 HR
SIL G-25 Tenside
•
High purity silica 60,
specific surface (BET) ~500m2/g, mean pore size 60 Å,
Specific pore volume 0.75mL/g, particle size 5 - 17 µm
Different binder systemcompared to SIL G results in different separation characteristics
®
• A special feature of the POLYGRAM SIL N-HR is higher
gypsumcontent.
• High purity silica 60 with gypsumand a very small quantity of a polymeric organic binder
Softer than the standard silica layer, i.e. spots can be scratched and the layer absorbs faster
•
Recommended application:
aflatoxins
• Silica G impregnated with ammonium sulfate. Recommended for the separation of detergents,
alkanesulfonates, polyglycols etc.
