Comprehensive two-dimensional gas chromatography (GC × GC), an analytical insturment implemented two GC-columns with different polarity, has a superior resolution compared with comventional GC. GC × GC can mesure the compositions in complex samples in the area such as petrochemical, food and environment. GC × GC can identify and quantify 1000 over peaks in diesel fuel, so that these peaks can be classified various structual types and carbon numbers. Recently, two new techniques specialized to the petrochemical area are developed. LC-GC × GC can gain more detailed informations than the current GC × GC, becase saturates, olefins and 1, 2, 3 ring-numeber aromatics fractionated from the diesel oil by LC beforehand can separately measure by GC × GC. The other is the new device that introduce the specified fractions in about a few full-range sample produced from A/C in GC × GC. Future GC × GC will be useful to understand a relationship between sort properties and the structural factors, and to examine theorytically the decomposed reactions and hydrocracking against heavy oil.
