WebAbstract. Two-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. WebWhat is GCxGC? GCxGC ("GC by GC"), also known as Comprehensive Two-Dimensional Gas Chromatography, is a powerful analytic technique that utilizes two columns of differing phase selectivity connected by a modulation device. The set-up of GCxGC improves peak capacity, resolution, and detectability. On average, a GCxGC analysis has five times the ...
