Molecular interconversion behaviour in comprehensive two-dimensional gas chromatography [PDF]

Journal of Chromatography A, 2004
Comprehensive two-dimensional gas chromatography (GC x GC) is shown to provide information on dynamic molecular behaviour (interconversion), with the interconversion process occurring on both columns in the coupled-column experiment. The experiment requires suitable adjustment of both experimental conditions and relative dimensions of each of the ...
