When describing the behavior of real polymers, it is important to take into account that the molecules do not have a single molar mass only since they may have a more or less wide molar mass distribution (MMD). Therefore a retardation time spectrum should be given preference, since here, a single retardation time only is not sufficient for an appropriate analysis.
