摘要：

In comprehensive two-dimensional gas chromatography, the entire chromatogram eluting from the primary column is submitted to the secondary column for a second independent separation. The resulting two-dimensional chromatogram has peaks scattered about a plane rather than along a line. Peak capacity can be very large allowing much more complete separation of complex mixtures such as petroleum products. Moderately complex samples can be separated much more quickly than is possible with high-resolution one-dimensional gas chromatography. The method is a true hyphenated instrument analogous to gas chromatography-mass spectrometry.
