Abstract :
In order to improve the gas sensitivity, selectivity and the expansion of the gas detection components, we presents a kind of gaseous hydrocarbon sensor with optimization electronic circuit which is able to be easily carried and have a high sensitivity. The system obtained by gas acquisition and processing module and the gas sensor feedback signal to the electronic circuit processing module, then accurately display data to the computer. The sensor can directly measure the quantities of the gaseous hydrocarbon in the sample. The detection limit is 10-10g. It not only can be used to explore the gas and oil in sea, but also can be used to test the other over-trace gas.
