Results and Discussion All of the chromatograms were created by using the Zoex GC Image software. The GC×GC 2D and 3D chromatograms for kerosene are shown in Fig.1. The X-axis corresponds with the separation by the 1 st column which is based on differences in boiling point, and the Y-axis corresponds with the separation by the 2 nd column which is based on differences in polarity. Also, the colors in the chromatograms show the intensity of each peak. The intensity increases from light blue to yellow to red. The red color shows that the compound intensity is over the settings value for the maximum intensity.
