WebTwo-dimensional gas chromatography (GC×GC) is a powerful separation technique, allowing to reach unique separation resolution. GC×GC is thus well suited for the characterization of complex volatile and semi-volatile mixtures. This high peak capacity results from the addition of an extra GC dimension.

WebA peak shape for the solvent peak is observed as shown in figure 1. After installing a new column, the solvent is tailing very strong while normally the peak looks like the trunk of a tree. The tail of the peak contains residual solvent molecules that are injected after the main injection is done. Very often the tail is caused by a dead volume.
