Abstract
Disclosed is a micro gas chromatography system including a fluid feeder for feeding a fluid composed of a carrier gas and a gas mixture containing an analyte component to the next stage, a micro gas preconcentrator chip configured to concentrate and desorb the analyte component contained in the fluid, a micro gas chromatography chip including a micro separation column for separating the analyte component concentrated and desorbed by the micro gas preconcentrator chip, and a micro sensing unit including a micro thermal conductivity detection sensor configured to detect the analyte component separated by the micro gas chromatography chip.
