  …phase that is used for plane chromatography is physically held in place in or on a plane. Typically the stationary phase is attached to a plastic, metallic, or glass plate. Occasionally, a sheet of high-quality filter paper is used as the stationary phase. The sample is added as a spot…

  In this geometry the stationary phase is configured as a thin two-dimensional sheet. In paper chromatography a sheet or a narrow strip of paper serves as the stationary phase. In thin-layer chromatography a thin film of a stationary phase of solid particles bound…
