Plates composed of an inert substrate coated with a thin layer of adsorbent material and used in the separation and analysis of non-volatile mixtures. Common thin-layer chromatography adsorbents include silica gel, aluminum oxide (alumina), and cellulose.
Separate non-volatile mixtures with unmodified standard silica layers for TLC (Thin-Layer Chromatography). Standard SIL G Silica Layers on Alugram™ Aluminum Sheets UV254 come in a variety of sizes.
