Thin layer chromatography (TLC) is a method that uses a thin layer made of a stationary phase such as silica gel, polyamide, alumina, etc. on a glass or aluminum plate, separates the mixture sample into each component with a mobile phase. TLC is widely used for substance identification, purity testing, and for examining separation conditions when using column chromatography. Fujifilm Wako provides TLC plates for simple analysis, preparative separation and purification, coated with various stationary phases according to the purpose.
