Chromatography is a way of separating out a mixture of chemicals. If you ever got a paper with ink wet you would have seen the ink move across the page in streaks. Capillary action makes the marker dye move up the paper towel. The water moves upward through the paper towel, lifting the washable dye molecules with it.
Molecules that are the most soluble will move the furthest and the least soluble will travel the shortest and are measured in retention time. The water itself is able to move up the paper due to the properties of water creating Capillary Action. In paper chromatography, the stationary phase is the paper and the mobile phase is the water.
