<p>In a two-dimensional gas chromatography system (200), it is necessary to "pair" peaks (1A1, 1A2, 1A3, 1A4, 1A5) from one chromatogram with respective peaks (1B1, 1B2, 1B3, 1B4, 1B5, 1B6) of another chromatogram. Both peaks of a pair should correspond to the same sample component. Confirmation or disconfirmation of pairs may be speculative or arbitrary. A hybrid chromatographic column (2AB) is designed so that the retention time of a sample component is the average of the retention times of that component in the two independent columns (2AA, 2BB). Thus, a peak location in the hybrid chromatogram can be calculated for each pair of peaks. The absence of a peak at that location or the inconsistency of the area of a peak at that location disconfirms the pairing. Higher dimensional systems and other separation technologies may also be used. <IMAGE></p> |
