Background technology
Gas detection method is numerous, during early stage war or the miners that open a mine once used canary (canary) to detect airborne trace toxic gas.Along with development of science and technology, people do not re-use the exploration of animal as toxic gas, and then develop and gas-monitoring instrument miscellaneous.That generally knows has chemical absorbing (chemicalabsorption), electrochemical sensor (electrochemical sensor), Jia Fani battery (GalvanicCell) sensor and gas chromatograph (gas chromatography), a mass spectrometer etc., in response to different demands by development for the different environment different types of gas of monitoring down.
Below will introduce several frequently seen air monitor, semiconductor sensor, infrared sensor, and novel carbon nanotube detector.
Semiconductor sensor head sees 1964, utilizes zirconium dioxide and tin oxide as air sensor material, and the advantage that cheap price and durability period are long has been included many on the market at present flammable gases and carbon monoxide siren commodity market.Semiconductor as its name suggests, characteristic in its conductivity between conductor and insulator.When gas to be measured passes through substrate surface,, for example will form the variation of base material conductive characteristic to semiconductor because adsorption reaction will cause the variation of base material rerum natura.Understand the concentration of the gas of monitoring by the variation of its conductive characteristic of monitoring.Yet, variations in temperature to monitoring result influence excessive and power consumption cross high reason and limited the development of semiconductor sensor on the portable type air monitor.The development gradually of rice science and technology along with how, the processing procedure of this type of semi-conducting material is also always in improved state, compared to some irretrievable sensing materials in use back such as electrochemical materials, the semi-conducting material that reclaims still has the space of its development on the portable type air monitor easily.
In the optical gas analyzer maturation just gradually based on infrared ray (infrared), use principle is that utilization gas reaches quantitative purpose to the characteristic that the absorption characteristic and the gas concentration of infrared ray special wavelength is directly proportional with uptake within the specific limits; In addition, if detect multiple gases simultaneously, and detected gas will be used the optical sensor of Different Light (double-beam or multi-beam) when ultrared absorption characteristic is had bigger difference.Infrared sensor is common in analyzes hydrocarbon (hydrocarbons), because of it has the characteristic that needn't contact with air to be measured, therefore often is used to chimney exhaust monitoring, tool gas-monitoring far away etc.Yet the miniaturization of infrared sensor is difficult for, and the expensive factor of price, makes it more rare on portable air monitor market.
In recent years how rice science and technology like a raging fire in fever all over the world, relevant application is also being developed always.U.S. Ashish Modi develops a cover and utilize the formed detector of carbon nanotube.This detector basic framework is a carbon nanotube array of growing up on the silicon dioxide substrate, and each carbon nanotube tip radius has only 15nm, is about 50nm to each other apart.150 μ m sentence aluminium as the another one electrode above carbon nanotube.Because carbon nanotube taper very, therefore electric field strength in its vicinity is quite big, provides very low voltage gas molecule can be dissociated and turning circuit.Find that after deliberation different gas molecules has different breakdownvoltage, therefore utilize the size of breakdown voltage, can determine the kind of gas molecule.In addition, there is good exponential relationship corresponding between size of current and gas concentration, therefore can comes gas to be measured is carried out quantitatively by size of current.Because suitable low of the needed operating voltage of carbon nanotube detector, with an electrode spacing spacing is that the carbon nanotube detector of 25 μ m is an example, the operating voltage of offer 130V can the free gas molecule, this voltage swing can provide by general battery, therefore helps to develop portable detector.
In sum, develop difficult many that a Portable gas monitor will face, except needs overcome operating voltage; Also have the restriction of detected gas kind, often a cover instrument can only detect one or two kind of gas, and the integrated air quality estimating in a sample district needs the detection data of multiple gases, and therefore how reaching the multiple gases detection fast also is one of problem to be solved.Present more existing large-scale far infrareds detections move development and come out to detect simultaneously for a long time multiple air pollution gas, but the character of expensive cost and mobile inconvenience makes this quasi-instrument generally use less being used.In addition, the detection of gas or the monitoring of air need all that the sampling of multiple spot and passback are rapidly upgraded, reporting chain, develop convenient move and the detector of fast changeable and the system that a cover can carry out data link rapidly also are one of directions of development at present.
