Abstract

Abstract

In order to improve the sensitivity and selectivity and to increase the detectable gas compositions, the chemical gas sensor is investigated and applied to explore natural gas and oil in sea. The sensor has the advantage over the traditional equipments, including high sensitivity, small magnitude, low weight, low power, easy manipulation, and also being able to work under the worst condition in sea. Different kinds of sensors are able to be installed on a chip, simultaneously testing diverse chemicals. The sensor can also be connected to the computer, directly process the data. Thus, it is specially suitable for exploring gas and oil in sea. Based on the chemical sensors, this sensor is the first detection system successfully investigated for the gaseous hydrocarbon and hydrogen in the world, which is able to be easily carried with high sensitivity. The sensor can directly measure the quantities of the over-trace methane, ethane, propane and hydrogen in the sample. The detection limit is 10^-10 g. Its selectivity, repeatability, stability and life-time have reached to the advanced level in the world. Not only can the sensor be used to explore gas and oil in sea, but also can be used to test other over-trace gases in any field.
