Description
Technical field
The utility model relates to a kind of atmosphere sampler field, relates in particular to a kind of atmospheric sampling equipment that possesses the temperature adjusting function that can automatically switch, carry out the sampling of many absorption bottles and preservation.
Background technology
Atmospheric sampling is the process that gathers pollutant sample in atmosphere or contaminated air sample.The spot sampling method has two classes: a class is to make large quantity of air pass through liquid-absorbant or solid adsorbent, and the enriching pollutants that concentration in atmosphere is lower gets up, as degassing method, filter membrane method.Another kind of is the air that contains pollutant with container (vial, polybag etc.) collection.What the former recorded is the mean concentration of pollutant in interior atmosphere of sampling time; What the latter recorded is the mean concentration in instantaneous concentration or short time.The mode of sampling should be determined according to purpose and the field condition of sampling.Institute's sample thief should be representative.It is high that sampling efficiency is wanted, and operation must be easy, and be convenient to carry out analysis mensuration subsequently, to obtain the master data of reliable atmospheric pollution.Gather the sample of pollutant in atmosphere or the sample of contaminated air, to obtaining the master data of atmospheric pollution.
Atmospheric sampling is the important step of atmosphere environment supervision, very big for the reliability relation of Monitoring Data.Gather the method for atmospheric sample, mainly contain two classes: a class is to make large quantity of air pass through liquid-absorbant or solid adsorbent, to absorb or the detention pollutant, the lower enriching pollutants of concentration in original atmosphere is got up, as degassing method, filter membrane method.The result recorded by these class methods is the mean concentration of pollutant in atmosphere in the sampling time.Another kind of is the air that contains pollutant with container (vial, polybag, rubber bladders, syringe etc.) collection.These class methods are applicable to following situation: in atmosphere, the concentration of pollutant is higher; Or the sensitivity of assay method is higher; Be difficult for the dusty gas and the steam that are absorbed by liquid-absorbant or solid adsorbent adsorbs.The instantaneous concentration that the result recorded by this method is pollutant in atmosphere or the mean concentration in the short time.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.Absorbing agent commonly used has: water, compound water solution, organic solvent etc.Chemical reaction must occur fast or can promptly dissolve pollutant with pollutant in absorbing agent, and is convenient to carry out analysis operation.For example airborne hydrogen fluoride, hydrogen chloride available water are as absorbing agent; Sulphuric dioxide can be with tetrachloro mercury sodium as absorbing agent; The organophosphorus pesticides such as thimet (3911), demeton (1059) can be with 5% methyl alcohol as absorbing agent etc.Solid adsorbent has two kinds of granular adsorbent and Fibriform adsorbents.Granular adsorbent commonly used 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 suction-operated is mainly the detention of physical property, for gathering particle.Sometimes adsorbent is first used 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 will, according to purpose and the field condition of sampling, be selected suitable sample mode.As continuous or instantaneous sampling, in ground grab sampling or the sampling of flowing, with balloon, aircraft, sample in the air, and environment sampling, indoor sampling and pollution source sampling etc.The sampling purpose is different with sample mode, and the method for sampling used and sampling thief are also different.As chimney endoparticle thing sampling, can be according to the chimney shape, highly, the punching of selected appropriate location, stretch into the gatherer of sampling thief in hole, with the collection of bleeding of dynamic speed such as grade.This method is called the isokinetic sampling method.
The sample that atmospheric sampling gathers should be representative.It is high that the efficiency of sampling is wanted, and operation must be easy, and the chemical analysis of being convenient to carry out is subsequently measured.The representational factor that affects sample has the efficiency of sampling thief and absorbing agent, and the position of sampled point and sampling thief are to interference of air-flow etc.
In recent years, the atmospheric sampling technology combines with analysis and testing technology just gradually, forms a kind ofly can be sampled continuously and automatically, analyze mensuration, record the device of measured result.This device can directly 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 to release new product, as: intelligent type atmospheric sampling thief, explosion-proof air sampler, two gas circuit air samplers etc. product has greatly enriched the classification of air sampler.
