Abstract
The invention relates to a method for simultaneously analyzing at least two samples using a chromatography device comprising a chromatography column having an inlet and an outlet, and at least one detector placed at the outlet of the chromatography column, the method comprising steps of: injecting fractions of each independent sample at the inlet of the chromatography column, the fractions of each independent sample being injected according to a specific injection timing sequence derived from a pseudo-random binary sequence associated with said independent sample; recording a signal generated by said detector for a period of time at least equal to a duration of the longest of the specific injection timing sequences; cross-correlating the recorded signal and a derived correlation function, said derived correlation function being derived from the pseudo-random binary sequence associated with one of the independent samples, so as to obtain an individual correlogram signal specific to said independent sample; and analyzing data of interest of the individual correlogram signal so as to obtain an output signal indicative of a composition of the sample.
