    摘要: The method comprises the following steps: injecting (100) a sample into a capillary; transporting (110) the sample along the capillary in experimental conditions suited to generate a Taylor dispersion phenomenon; generating (120) a signal characteristic of the Taylor dispersion; processing (130) the signal in order to obtain the experimental Taylor signal Ŝ(t); and analysing (200) the experimental Taylor signal Ŝ(t), The analysis step consists of seeking an amplitude distribution P(G(c)) that allows the experimental Taylor signal Ŝ(t) to be broken down into a sum of Gaussian functions by implementing a constrained regularization algorithm consisting of minimising a cost function Hα including at least one constraint term associated with a constraint that must observe the amplitude distribution P(G(c)) , whereby the minimization is carried out on an interval of interest of the values of the parameter G(c) that is characteristic of the Gaussian amplitude function P(G(c)).
