When the price elasticity of demand for a good is relatively inelastic (-1 < Ed < 0), the percentage change in quantity demanded is smaller than that in price. Hence, when the price is raised, the total revenue increases, and vice versa.
The inevitable broadening of peaks during the chromatographic process may make it difficult to discern two consecutive peaks in a chromatogram from each other. Such a situation will occur if the peaks overlap extensively. The ability to resolve two consecutive peaks is defined as the resolution and is given by; The widths of the two closely eluting peaks are nearly equal. For quantitative work a clear separation of peaks is necessary. However it is not necessary to have a large separation between the peaks (overkill).
in separation and purification: Chromatography. ...mobile. Typically, the stationary phase is a porous solid (e.g., glass, silica, or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary. The mobile phase flows through the packed bed or column.
