    • 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.
    • 本发明是通过二维气相色谱法对分子化合物的混合物进行定量分析的方法,其用于定量分析来自化学或石油工业的产物。 进行二维气相色谱,在此期间记录色谱信号。 从信号中产生色谱峰形成斑点的二维色谱图。 这些点是通过多边形定义的。 然后,对于每个多边形,提取包含多边形的两个交点与色谱图列之间的色谱信号部分。 对这些部分中存在的色谱峰定义开始和结束时间,并根据色谱峰的开始和结束时间移动其交点来调整多边形。 最后,通过计算如此调整的多边形的表面积来确定分子化合物量。
