    摘要: The Invention is a method for quantitative analysis of a mixture of molecular compounds by two-dimensional gas chromatography having application for quantitative analysis of products from the chemical or petroleum industry. A two-dimensional gas chromatography is carried out, during which a chromatographic signal is recorded. A chromatogram in two dimensions on which chromatographic peaks form spots is generated from the signal. These spots are defined by means of polygons. Then, for each polygon, chromatographic signal portions contained between two intersections of the polygon with columns of the chromatogram are extracted. Start and end times are defined for the chromatographic peaks present in these portions and the polygon is adjusted by shifting its intersection points according to the start and end times of the chromatographic peaks. Finally, molecular compound amounts are determined by calculating the surface area of the polygons thus adjusted.
