Abstract
There is provided a sample preconcentrator. The sample preconcentrator in which a sample gas injection port is coupled to a dried gas supply source and a gas analysis system to concentrate a sample gas comprises a sample concentrating unit containing an absorbent that is composed of carbon nanotube-metal nanocomplex; a conduit switching valve for selectively coupling the sample gas injection port to the dried gas supply source and the gas analysis system and controlling the absorption and desorption of the sample gas from the sample concentrating unit; and a plurality of conduits for connecting the sample gas injection port, the dried gas supply source, the gas analysis system, the sample concentrating unit and the conduit switching valve.
