Temperature-tunable selectivity in comprehensive two-dimensional gas chromatography [PDF]

Journal of Chromatography A, 2012
A temperature-tunable two-dimensional gas chromatography setup, consisting of three capillary columns with different selectivity, is described. In this setup the selectivity of the primary dimension can be tuned by adjusting the temperature offset of two in series-coupled capillary columns, both columns being part of the primary dimension and ...
