Description
Technical field:
The invention belongs to gas toxic biological detection technique field, be specifically related to a kind of portable air toxicity raw
Analyte detection device, it is adaptable to rescue and relief work, geological exploration, travel life, field rescue, industrial environment inspection
Survey, urban waste gas detection, underground installation environmental monitoring, domestic environment detection etc., it is possible to effectively detect sky
Whether gas contains noxious material.
Background technology:
Produce or life process in, have the factors such as numerous physics, chemistry, biology threaten human life and
Property safety, one of most important of which stealth killer is toxic and harmful, common are chlorine, light
Gas, surpalite, sulfur dioxide, nitrogen oxides, formaldehyde, ammonia, ozone, carbon monoxide, hydrogen sulfide,
The thousands of kinds of different toxic and harmfuls that and laboratory industrial with hydrocyanic acid etc. produces, owing to major part has poison gas
Body colorless and odorless, people are difficult to discover for the moment, but are chronically at and the most then can cause slow poisoning.In recent years
The most serious with industrial expansion air pollution, haze, PM2.5, dust, vehicle exhaust, formaldehyde,
What's frequently heard can be repeated in detail already for the nouns such as nitrogen oxides, big discharges to industrial waste gas, little to life staying idle at home finishing,
The problems such as dismounting, gas leak, all affect the normal life of people, but existing gas detection equipment
All there is detection range not wide spectrum, it is impossible to be detected simultaneously by air defects such as biological poisonous and hazardous materials.
The most general is to represent the pollution level of air, i.e. surrounding air with air pollution index PM 2.5
The content concn of the middle aerodynamics equivalent diameter particulate matter less than or equal to 2.5 microns, it contains in atmosphere
Amount concentration is the highest, just represents air pollution the most serious；But its scope is the most general, it is impossible to effective expression is empty
In gas, the concrete toxicity of poisonous and harmful substance and interaction between it, more can not accurately measure much dense
People's existence it has been unsuitable in the range of degree.Although prior art exists numerous gas measuring apparatus, analysis
Equipment, but the choosing of the undispersed infrared method used, gas chromatography, the Saltzman method of improvement, ion
Select the method such as electrode method, formaldehyde absorption-Pararosaniline AAS, be used for detect carbon monoxide, benzene,
During the toxic and harmfuls such as toluene, dimethylbenzene, two change nitrogen, sulfur dioxide, ammonia, all can only realize the most several
The detection of item gas, pernicious gas detection spectrum is narrow, not only can not accomplish comprehensive covering of various toxic gas,
And cost is high, it is big to spend, the time is long, it is difficult to be generally applicable in daily life.Such as Chinese patent
