Is chromaplate a part of TLC?

Yes, chromaplate is a type of stationary phase used in thin-layer chromatography (TLC). It typically consists of a glass or plastic plate coated with a thin layer of adsorbent material, such as silica gel or alumina, which is used to separate compounds based on their interactions with the stationary phase and the mobile phase. Chromaplate facilitates the visualization and analysis of different substances in a mixture as they move across the plate.
