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 Segmented thermal modulators were fabricated for the modulation of column effluent in oneβdimensional gas chromatography, comprehensive twoβdimensional gas chromatography, and as sample introduction devices in other analytical techniques. Thermal desorption of analytes from the modulato
At-column heating and a resistively heated, liquid-cooled thermal modulator for a low-resource bench-top GC6GC A transportable GC6GC instrument is under development for on-site applications that would benefit from the enhanced resolution and powers of detection, which can be achieved by this method
