Power fit of theoretical retention curves. A–E Theoretical retention curve computed with equation (9) for \(n=5\), plotted for different time windows. In the inset the estimated value of the power α for the corresponding window is shown. F The dependence of α on time (orange curve). The value of α very slowly approaches −1, so that even for \(T=10^{8}\), it is still about −0.8. For comparison, the asymptotic estimate of α given by equation (14) is shown in blue
