Two-Dimensional Gas Chromatography. Concepts, Instrumentation, and Applications - Part 2: Comprehensive Two-Dimensional Gas Chromatography

“…Others find that it is more important to emphasize the multiplicative aspects of peak capacity enhancement. Only two reviews [144,145] and approximately 25 publications are available on this new development. Applications have essentially been limited to the analysis of petroleum distillates.…”

Low cost, robust, in‐house hardware for heart cutting two‐dimensional gas chromatography

“…While comprehensive GC is able to produce a 2-D separation for a whole chromatogram in one run, the need for a very rapid second dimension separation dictates the use of short, narrow-bore, second dimension columns with linear gas flow rates substantially above the optimum. In practise, the second dimension columns generate only about 2500 effective plates [13], and can separate 5-10 peaks [7,14] that are so narrow that they require fast detectors and mass spectrometers [15][16][17], which with the present state of the art cannot provide accurate masses. In addition, and critically for flavour and fragrance work, GC-olfactometry has not been demonstrated to be possible after comprehensive separations.…”
