CHROMOTOGRAPHY Chromatography is used to separate mixtures of substances into their components. All forms of chromatography work on the same principle that they all have a stationary phase (a solid or a liquid supported on a solid) and a mobile phase where liquid or a gas is involved. The mobile phase flows through the stationary phase and carries the components of the mixtures with it. Different components travel at different rates. In paper chromatography‚ the stationary phase is a very uniform

Gas Chromatography (GC) Definition: Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases‚ one being a stationary bed of large surface area‚ and the other a gas that percolates through the stationary bed. When the stationary phase is a solid‚ the separation process is more precisely called gas-solid chromatography. Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds
