In mathematics and statistics, a stationary process (or strict(ly) stationary process or strong(ly) stationary process) is a stochastic process whose joint probability distribution does not change when shifted in time.
Mobile phase is a medium used in chromatography which moves through the stationary phase. In TLC and column chromatography, the mobile phase is an organic liquid. In Gas Chromatography the mobile phase is a gas. Stationary phase is a material used in chromatography which does not move. The mobile phase passes through the stationary phase. The stationary phase is either a pure solid substance such as alumina or silica or a thin coating of liquid on a solid support or a gel. In TLC the stationary phase is a spread in a thin layer on an inert support, usually a plastic sheet or a glass plate. The mobile phase moves upward by capillary action.
