Abstract:
1. A method for quantitative analysis of a mixture of molecular compounds by two-dimensional gas chromatography using a two-dimensional gas chromatography device, wherein a chromatogram in two dimensions is generated from a chromatographic signal provided by a detector and chromatographic peaks are selected by means of polygons, comprising for at least one polygon: (a) adjusting with a processor each polygon by identifying portions of the chromatographic signal contained in each polygon determining start times, end times and maximums for chromatographic peaks present in the portions; and adjusting each polygon with a processor by shifting intersection points between each polygon and the portions, according to the start times, the end times and the maximums of the chromatographic peaks; and (b) determining an amount of at least one molecular compound by calculating the surface area of the adjusted at least one polygon.
