Abstract
A chromatograph is provided for identifying components of a mixture. Components are identified by different rates of adsorption and/or desorption with a material phase. In one embodiment, an electrical lead is connected to the material phase for supplying an electrical charge to the material phase. The electrical charge alters the rate of adsorption/desorption of the components with the material phase. In another embodiment, the material phase is disposed between two conductors with electrical leads connected to each of the conductors. A charge differential between the two conductors alters the rate of adsorption and/or desorption of components with the material phase.
