| Abstract: | "In this paper, a micro gas chromatography (muGC) system contained a muGC column and a micro thermal conductivity detector (muTCD) was proposed. In order to reduce the volume of the system, some micro heaters were integrated on the surface and backside of the GC column, which could provide a robust temperature programming capability and rapidly increase the temperature of the muGC column. In addition, a silicon-glass muTCD with four-thermistor thermal conductivity cells that can offer significant advantages over previously reported designs including low dead volume, good thermal isolation, and elimination of the thermal noise was proposed in this paper. Experimental results have indicated that the muGC system with a detection limit of several ppm concentration levels separated and detected the benzene, toluene, and styrene in less than 3 min, and the muGC system also exhibited a good linear response in the test range" |
