WebThe TLC stationary phase consists of a TLC plate coated with a layer of sorbent material. TLC layers can be prepared in the lab, but they are normally purchased as pre-coated plates. There is a diverse range of options available – from silica, aluminum oxide or cellulose, to modified or mixed-layer plates. WebMar 16, 2024 · There is a stationary phase, the material that separates the components of the mixture, and finally, there is the mobile phase, which moves through the stationary phase and carries the sample across it. In TLC, the stationary phase is an aluminium or glass plate covered in silica (often impregnated with a florescent dye to aid visualisation).
