In the case of Thin Layer Chromatography (TLC) a drop of the sample to be tested is placed on a plate of silica gel containing a chromaphore (a UV active substance). The end of the plate with the drop of sample is placed into the mobile phase. The mobile phase will travel up the plate taking with it the components of the sample. The smaller the component the further it will travel. This can then be viewed using a UV light.
