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).
resolution will be in the range of micrometers, but the maximum range is limited to only a few meters. Up to distances of 100m people often use the phase shift measurement. The laser light is modulated and the phaseshift between outgoing and incoming light gives the distance. To reach a resolution in the millimeter range very high sampling rates are necessary. Only low measuring rates with high current consumtion are possible the consequence. With Time-to-Digital-Converters (TDCâs) you choose the straight way. It is possible to measure directly the time-of-flight of light.
