In comprehensive two-dimensional gas chromatography (GC6GC), two capillary columns are connected in series through an interface known as a "thermal modulator". This device transforms effluent from the first capillary column into a series of sharp injection-like chemical pulses suitable for high-spee
## Abstract The modulation system in a comprehensive two‐dimensional gas chromatograph (GC×GC) can be regarded to be the heart of the analyzer. Different ways of modulating the effluent of the first column into very narrow pulses and injecting these onto the fast second column have been demonstrate
## Abstract Many modulation systems in comprehensive 2D GC (GC×GC) are based on cryogenic methods. High trapping temperatures in these systems can result in ineffective trapping of the more volatile compounds, whilst temperatures that are too low can prevent efficient remobilisation of some compoun
