FIELD: identification of individual compounds. SUBSTANCE: investigated matter is simultaneously dosed into two or more chromatographic columns connected in parallel with stationary liquid phases different in molecular structure and character of interaction with analyzed matters. Signals of detector on one chromatograms in the form of spectrum of peaks of analyzed matter shifted in time in proportion to values of confinement on each column are registered. Batcher is provided with number of doses of different fixed volume and inlet of each of columns is connected to fixed dose and line of gas carrier through shut-off elements of batcher. Belonging of each peak of spectrum to proper column is judged by absolute value of chromatographic signal of detector at outlet of columns. EFFECT: improved efficiency of method for identification of complex mixtures. 2 cl, 2 dwg
