Description
Technical field
The present invention relates to a kind of atmosphere sampler field, particularly relate to a kind of atmospheric sampling equipment that can automatically switch, carry out the sampling of many absorption bottles and preservation.
Background technology
Atmospheric sampling is the process gathering pollutant sample or contaminated air sample in air.Spot sampling method has two classes: a class makes large quantity of air by liquid-absorbant or solid adsorbent, got up by enriching pollutants lower for concentration in air, as degassing method, filter membrane method.Another kind of is the air containing pollutant with container (vial, polybag etc.) collection.The mean concentration of what the former recorded is pollutant in air in the sampling time; What the latter recorded is instantaneous concentration or the mean concentration in the short time.The mode of sampling should be determined according to the object of sampling and field condition.Institute's sample thief should be representative.Sampling efficiency wants high, and operation must be easy, and is convenient to the analysis carried out subsequently and measures, to obtain the master data of reliable atmospheric pollution.Gather the sample of pollutant or the sample of contaminated air in air, to obtaining the master data of atmospheric pollution.
Atmospheric sampling is the important step of atmosphere environment supervision, and the reliability relation for Monitoring Data is very big.Gather the method for atmospheric sample, mainly contain two classes: a class makes large quantity of air by liquid-absorbant or solid adsorbent, to absorb or detention pollutant, enriching pollutants lower for concentration in original air got up, as degassing method, filter membrane method.By the mean concentration that the result that these class methods record is pollutant in air in the sampling time.Another kind of is the air containing pollutant with container (vial, polybag, rubber bladders, syringe etc.) collection.These class methods are applicable to following situation: in air, the concentration of pollutant is higher; Or the sensitivity of assay method is higher; Not easily absorbed by liquid-absorbant or solid adsorbent absorption dusty gas and steam.The result recorded by this method is the instantaneous concentration of pollutant or the mean concentration in the short time in air.In addition, also have low-temperature freezing, can be used for gathering escaping gas and steam, as alkyl lead.Liquid-absorbant in sampling thief is mainly used in absorbing gaseous state and steam-like material.Conventional absorbing agent has: water, compound water solution, organic solvent etc.Must there is chemical reaction or pollutant promptly can be dissolved fast with pollutant in absorbing agent, and be convenient to carry out analysis operation.Such as, hydrogen fluoride in air, hydrogen chloride available water are as absorbing agent; Sulphuric dioxide can with tetrachloro mercury sodium as absorbing agent; The organophosphorus pesticides such as thimet (3911), demeton (1059) can with 5% methyl alcohol as absorbing agent etc.Solid adsorbent has granular adsorbent and Fibriform adsorbents two kinds.Conventional granular adsorbent has silica gel, unglazed pottery etc., for the sampling of gaseous state, steam-like and particle.Fibriform adsorbents has filter paper, filter membrane, absorbent cotton, glass wool etc., and the detention of suction-operated mainly physical property, for gathering particle.Sometimes adsorbent is first by certain chemical reagent dip treating, makes pollutant with it, chemical action occur and be adsorbed, and is mainly used in gathering gaseous state or steam-like pollutant.
Atmospheric sampling according to the object of sampling and field condition, will select suitable sample mode.As continuous or instantaneous sampling, in ground grab sampling or flowing sampling, sample in the air with balloon, aircraft, and Environment features, indoor sampling and pollution source sampling etc.Sampling object is different with sample mode, and the method for sampling used and sampling thief are also different.As the sampling of chimney endoparticle thing, can according to chimney shape, highly, the punching of selected appropriate location, stretch into the gatherer of sampling thief in hole, to bleed collection with waiting dynamic speed.This method is called isokinetic sampling method.
The sample that atmospheric sampling gathers should be representative.The efficiency of sampling wants high, and operation must be easy, and is convenient to the chemical analysis carried out subsequently and measures.Affect the representational efficiency because have sampling thief and absorbing agent of sample, the position of sampled point and sampling thief are to the interference etc. of air-flow.
In recent years, atmospheric sampling technology combines with analysis and testing technology just gradually, forms a kind of device that can carry out sampling, analyze mensuration, record measured result continuously and automatically.This device directly can carry out field monitoring, is called monitoring analyzer.
Air sampler plays a good role for the detection of harmful gas in air and environment.Along with the continuous progress of science and technology, air sampler is also constantly release new product, as: intelligent type atmospheric sampling thief, explosion-proof air sampler, two gas circuit air sampler etc. product, has greatly enriched the classification of air sampler.
The atmospheric sampling equipment that can automatically switch, carry out the sampling of many absorption bottles constant-temperature constant-current and preserve not a kind of in existing sample devices.
