Abstract: The thin layer chromatography plate includes a substrate and a separation layer. The separation layer is disposed on the substrate and is configured to separate multiple components included in a sample from each other. The separation layer includes a first layer and a second layer. The first layer has a porous structure and extends in a first direction. The second layer has a porous structure and extends in the first direction. The first layer and the second layer are arrayed in a second direction orthogonal to the first direction. A zeta potential of the first layer is different from a zeta potential of the second layer.
