Description
Technical field
The present invention relates to a kind of atmospheric sampling device field, relate in particular to a kind of atmospheric sampling equipment that can automatically switch, carry out many absorption bottle samplings and preserve.
Background technology
Atmospheric sampling is the process of gathering pollutant sample in the atmosphere or contaminated air sample.The spot sampling method has two classes: a class is to make a large amount of air by liquid-absorbant or solid adsorbent, and the enriching pollutants that concentration in the 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 the interior atmosphere of sampling time; What the latter recorded is instantaneous concentration or interior mean concentration of short time.The mode of sampling should be decided 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 assay determination subsequently, to obtain the master data of reliable atmospheric pollution.Gather the sample of pollutant in the atmosphere or the sample of contaminated air, in the hope of obtaining the master data of atmospheric pollution.
Atmospheric sampling is the important step of atmosphere environment supervision, and is very big for the reliability relation of Monitoring Data.Gather the method for atmospheric sample, mainly contain two classes: a class is to make a large amount of air by liquid-absorbant or solid adsorbent, to absorb or the detention pollutant, the lower enriching pollutants of concentration in the original atmosphere is got up, as degassing method, filter membrane method.The result who records with these class methods is the mean concentration of pollutant in the 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: the concentration of pollutant is higher in the atmosphere; Or the sensitivity of assay method is higher; Be difficult for being absorbed by liquid-absorbant or dusty gas and the steam of solid adsorbent absorption.The result who records with this method is the instantaneous concentration of pollutant in the 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 the 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 take place fast with pollutant or can promptly dissolve 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; Thimet (3911), demeton organophosphorus pesticides such as (1059) can be with 5% methyl alcohol as absorbing agents etc.Solid adsorbent has two kinds in granular adsorption agent and fibrous adsorbent.Granular adsorption agent commonly used has silica gel, unglazed pottery etc., is used for the sampling of gaseous state, steam-like and particle.Fibrous adsorbent has filter paper, filter membrane, absorbent cotton, glass wool etc., and suction-operated mainly is the detention of physical property, is used for gathering particle.Sometimes adsorbent is earlier with certain chemical reagent dip treating, makes pollutant with its generation chemical action and is adsorbed, and is mainly used in gathering gaseous state or steam-like pollutant.
Atmospheric sampling will be selected suitable sample mode according to purpose and the field condition of sampling.As continuous or instantaneous sampling, in ground grab sampling or the sampling of flowing, sample in the air with balloon, aircraft, and environment sampling, indoor sampling and pollution source sampling etc.The sampling purpose is different with sample mode, and the used method of sampling 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 is stretched into the gatherer of sampling thief in the hole, with the collection of bleeding of speed such as power such as grade.This method is called the isokinetic sampling method.
The sample that atmospheric sampling is gathered should be representative.It is high that the efficient 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 influences sample has the efficient 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, constitute a kind ofly can sample continuously and automatically, the device of assay determination, record 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 the environment.Along with continuous progress in science and technology, air sampler also is 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.
