WebThe stationary phase method is an approach for solving integrals analytically by evaluating the integrands in regions where they contribute the most. This method is specifically directed to evaluating oscillatory integrands, where the phase function of the integrand is multiplied by a relatively high value. Webchromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid. Webstationary phase, in analytical chemistry, the phase over which the mobile phase passes in the technique of chromatography.
