Comprehensive Two-Dimensional Gas Chromatography (GCxGC)

Advanced GC technique that separates compounds using two columns with different properties for enhanced resolution.

Peter Gorst-Allman [LECO] discusses the usage of GCxGC TOF-MS (with the Pegasus BT 4D) to analyze dioxins in samples, in accordance to EPA 1613.
