摘要
A two-dimensional gas chromatography system having first and second separation columns, a thermal modulator disposed between the first and second columns and having a plurality of stage channels, and a micro heater monolithically integrated in the thermal modulator. The thermal modulator is operable to trap and focus gas/vapor species within the plurality of stage channels upon cooling and release the gas/vapor species to the second column upon heating by the micro heater.
