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.
Claims15
A micro gas chromatography system comprising:
- a fluid feeder configured to feed a fluid composed of a carrier gas and a gas mixture containing at least one analyte component to a micro gas preconcentrator chip;
- the micro gas preconcentrator chip configured to concentrate and desorb the analyte component contained in the fluid composed of the carrier gas and the gas mixture;
- a micro gas chromatography chip into which the fluid containing the analyte component desorbed from the micro gas preconcentrator chip is introduced and from which the analyte component contained in the fluid is separately eluted;
- and
- a micro sensing unit including a gas detector configured to detect the analyte component eluted from the micro gas chromatography chip,
- wherein the micro gas chromatography chip includes a micro separation column having a rectangular, circular, or serpentine micro-channel formed in one surface of a substrate, the micro-channel having a plurality of bumps formed on an inside wall surface thereof, wherein some of the bumps are formed on a first side of the inside wall surface of the micro-channel, the other bumps are formed on a second side that is opposite to the first side, and the bumps formed on the first side and the bumps formed on the second side are alternate with each other.
