Comprehensive two‐dimensional gas chromatography‐mass spectrometry: A review [PDF]

Mass Spectrometry Reviews, 2008
AbstractAlthough comprehensive two‐dimensional gas chromatography (GC × GC) has been on the scene for more than 15 years, it is still generally considered a relatively novel technique and is yet far from being fully established. The revolutionary aspect of GC × GC, with respect to classical multidimensional chromatography, is that the entire sample is ...
