title: Pixel-based analysis of comprehensive two-dimensional gas chromatograms (color plots) of petroleum: a tutorial.
abstract: We demonstrate how to process comprehensive two-dimensional gas chromatograms (GC × GC chromatograms) to remove nonsample information (artifacts), including background and retention time shifts. We also demonstrate how this, combined with further reduction of the influence of irrelevant information, allows for data analysis without integration or peak deconvolution (pixel-based analysis).
