Thin-layer chromatography (TLC) 1 Pack

Product Overview  Sigma-Aldrich TLC Platessilica gel matrix, L × W 20 cm × 20 cm 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.
