Description
Technical field
The utility model relates to air objectionable impurities detection technique field, particularly a kind of passive type air sampler that can be regularly.
Background technology
Under the normal pressure, the organic compound of boiling point in 50 ° to 260 ° scopes is referred to as VOC(volatile organic compounds), these organic compounds mainly comprise: benzene,toluene,xylene, ethylbenzene and styrene etc., because building materials, ornament materials, furniture, household electrical appliances have used the material that contains VOC and formaldehyde in a large number when producing, in use subsequently, these gases can progressively discharge and pollute indoor air ambient; In the environment that VOC or formaldehyde exceed standard, live, symptoms such as ocular pain, sore-throat, headache, tired out sense, dysphoria appear in regular meeting during the people of work, study, are referred to as " sick building syndrome ", can cause the dirty impaired or leukaemia of a plurality of devices when serious.
Each developed country of the world all pays much attention to this.China has put into effect " civil building engineering indoor environmental pollution control standard " in calendar year 2001, will not check and accept for the newly-built, renovating and enlarging building that exceeds standard at pollutants such as VOC or formaldehyde.
The general air sampler that adopts is gathered or is extracted the volatile organic compound (VOC) in the detected environment at present, and then air sampler and gas chromatograph be used in conjunction to detect tested airborne VOC concentration, air sampler is divided into active air sampler and passive type air sampler, so-called initiatively air sampler refers to by asepwirator pump and air-flow measurement device, the regular hour with the air sample of certain volume by the absorbing medium in the sampling thief, be adsorbed in the absorbing medium thereby VOC is concentrated, and then detect with concentration that gas chromatograph is used in conjunction VOC; The passive type air sampler is to utilize gas molecule diffusion or penetration theory to gather a kind of sampling thief of VOC in the air, mainly is that the regular hour (sampling time) is adsorbed in its inner adsorbent airborne a part of VOC in the detected air by its adsorbent is exposed to.Because in sampling time one timing, the amount of the VOC that adsorbs in the adsorbent and airborne VOC concentration are proportional; Airborne VOC concentration one regularly, amount and the sampling time of the VOC that adsorbs in the adsorbent are proportional, therefore measure in the absorbing agent VOC content then with the various sampling times under, various normal concentration down-sampling detects the relation curve that obtains and compares, and can detect the VOC concentration in the detected environment.
The detection method that the acceptance of work is at present adopted is active air sampling method, but this carries out data acquisition with regard to needing special testing staff to carry detecting instrument to the scene, need expend lot of manpower and material resources and time, thereby the detection cost of this kind detection method is higher, many families are hung back to Indoor Environment Detection, be not suitable for average family to the detection of room air.
The passive type air sampler only needs air sampler is placed on to sample in the testing environment get final product, thereby it can significantly reduce the detection cost, and still mainly there is following shortcoming in present passive type air sampler:
1) sampling time misregister, the sampling time of passive type air sampler is controlled and record by the domestic consumer, because domestic consumer's non-professionality, the sampling time of record may not be inconsistent with the sampling time of reality, thereby caused testing result deviation to occur;
2) the sampling back causes detection to be failed to the operation of passive type air sampler is lack of standardization easily, because domestic consumer's non-professionality, may have pollutant during " locked in " operation and enter into sealing bag, also or seal operation untimely or poorly sealed, all can cause detecting failure.
Therefore, how can improve the sampling precision of passive type air sampler, realize that the user to the sampling voluntarily of room air, with the popularity of actuating air sampling thief, is the technical matters that present those skilled in the art need solution badly.
