MilliporeSigma™ Supelco™ Sigma-Aldrich™ TLC Plates, Silica Gel Matrix, 200 μm

Description

• Thin-layer chromatography (TLC) plates for adsorption, partition, and ion-exchange techniques
• Six media choices with glass, polyester, and aluminum backings
• Silica-based adsorbent layers in Sigma-Aldrich TLC plates incorporate a polymeric binder; highly purified silica gel plates incorporate a gypsum/polymer binder
• Silica gel - for weakly to strongly polar separations, pore size 60 Å
• High purity silica gel - acid washed for separation of aflatoxins
• Cellulose - for partition chromatography, (SigmaCell Type 100 Cellulose)
• Cellulose PEI - for separation of weak anions (amino acids, peptides) PEI plates may turn slightly yellow, affecting separation
• Pre-develop plates in distilled water to minimize yellow color
• Chiral silica - for separation of optically active isomers by ligand exchange, pore size 60 Å.
