GCxGC (2DGC)

The total output of one GC capillary column is transferred in short pulses onto a second much shorter column, usually of a radically different stationary phase polarity. The separation on the second column is completed before the next pulse is transferred. This provides a huge increase in column efficiency and resolving power of the method, capable of separating around 5000 analytes. A high acquisition rate detector is required for this technique as very narrow peaks are produced, resulting in higher method sensitivity. Both columns are in tandem and are served by a single detector.
