This paper provides a short overview of the theory and practice of the rapidly-developing field of two-dimensional gas chromatography (GC×GC). Included in the discussion are a summary of the detectors used, an assessment of the options available for modulating the first-column eluate, and some recent developments in methodologies for interpreting the results.
SepSolve Analytical, in collaboration with Separation Science, is offering an eSeminar covering the principles and applications of two-dimensional gas chromatography (GC×GC). These presentations are available to view on-demand.
This paper provides a short overview of the drawbacks of split/splitless inlets used for GC, and how these can be tackled through large-volume injection (LVI) using the OPTIC-4 multi-mode inlet from GL Sciences.
