Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid (gas, solvent, water, ...) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which is fixed a material called the stationary phase.

Physical method used to separate mixtures. Mixture is distributed into two phases; a stationary phase and a mobile phase. The mobile phase moves through the stationary phase carrying the mixture. Each component in the mixture will have a different affinity for the stationary phase. It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper. It is a powerful analytical tool that uses very small quantities of material. Paper chromatography was discovered by Synge and Martin in the year 1943.

May 07, 2012 · Chromatography- the general name for a series of methods for separating mixtures by employing a system with a mobile phase (liquid or gas) and a stationary phase (solid) Chapter 2: Atoms, Molecules, and Ions. Law of definite proportions (aka Proust’s Law) – a given compound always contains exactly the proportions of element by mass. Chromatography is used to separate mixtures of substances into their components. All forms of chromatography work on the same principle. They all have a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas).Esri style geology
