    摘要: A method for identifying a convolved peak is described. A plurality of spectra is obtained. A multivariate analysis technique is used to assign data points from the plurality of spectra to a plurality of groups. A peak is selected from the plurality of spectra. If the peak includes data points assigned to two or more groups of the plurality of groups, the peak is identified as a convolved peak. Principal component analysis is one multivariate analysis technique that is used to assign data points. A number of principal components are selected. A subset principal component space is created. A data point in the subset principal component space is selected. A vector is extended from the origin of the subset principal component space to the data point. One or more data points within a spatial angle around the vector are assigned to a group.

    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.

    摘要: Deconvolution of up to three overlapping chromatographic peaks is provided in which pure spectral components are extrapolated from a Euclidean-normalized expression of chromatographic data in the space of the three principal factors. A coordinate transformation to planar coordinates after expansion in factor space and before extrapolation yields the simplicity of linear extrapolation in combination with the inherent accuracy of Euclidean, as opposed to standard, normalization. The estimation of the pure component spectra permits the constructions of a concentration matrix. Improved estimates and an error bound are provided by applying assumptions of non-negativity and limited deviation from the means to the concentration matrix.
