WebAug 15, 2024 · Thin layer chromatography is done exactly as it says - using a thin, uniform layer of silica gel or alumina coated onto a piece of glass, metal or rigid plastic. The silica gel (or the alumina) is the stationary phase. The stationary phase for thin layer chromatography also often contains a substance which fluoresces in UV light - for … WebThere are two phases of chemicals in chromatography, the stationary phase and the mobile phase. The stationary phase is the substance that is used in the "background" so as to carry the mobile phase molecules. The products in which one is trying to observe will travel in the mobile phase through the stationary phase.
