In this paper, we introduced a micro gas chromatography (GC) system, which integrated a micro GC column and a micro thermal conductivity detector (µTCD). The micro GC column with a high aspect ratio channel was integrated some micro-heaters which were placed on the surface and back of the micro GC column. These micro heaters can quickly enhance the temperature of the micro GC column with a ratio of 40/min, and the temperature can reach 140...
