Thoroughly cleaning, particle analyte detection pretreating device simple in structure, high degree of automation.
Background technology
Atmospheric sampling is the process of pollutant sample or contaminated air sample in acquisition air.Spot sampling method has two
Class：One kind is that large quantity of air is made to pass through liquid-absorbant or solid absorbent, and the lower enriching pollutants of concentration in air are risen
Come, such as degassing method, filter membrane method.Another kind of is to acquire the air containing pollutant with container (vial, polybag etc.).The former surveys
What is obtained is the mean concentration of pollutant in air in the sampling time；What the latter measured is instantaneous concentration or average dense in the short time
Degree.The mode of sampling should be depending on the purpose of sampling and field condition.Institute's sample thief is answered representative.Sampling efficiency wants high,
Operation must be easy, and is convenient for subsequent analysis and measures, to obtain the master data of reliable atmosphere pollution.Acquire air
The sample of middle pollutant or the sample of contaminated air, to obtain the master data of atmosphere pollution.
Atmospheric sampling is the important step of atmosphere environment supervision, very big for the reliable sexual intercourse of monitoring data.Acquisition is big
The method of gas sample product, there are two main classes:One kind is that large quantity of air is made to pass through liquid-absorbant or solid absorbent, to absorb or hinder
Pollutant is stayed, the lower enriching pollutants of concentration in original air are got up, such as degassing method, filter membrane method.It is measured with such methods
The result is that in the sampling time in air pollutant mean concentration.Another kind of is to use container (vial, polybag, rubber ball
Courage, syringe etc.) air of the acquisition containing pollutant.Such methods are suitable for following situations：In air the concentration of pollutant compared with
It is high；Or the sensitivity of assay method is higher；It is not easy by the polluted gas and steaming of liquid-absorbant absorption or solid absorbent absorption
Vapour.The result measured with this method is the instantaneous concentration of pollutant or the mean concentration in the short time in air.In addition, also low temperature
Freezing can be used for acquiring escaping gas and steam, such as alkyl lead.Liquid-absorbant in sampler is mainly used for absorbing gas
State and steam-like substance.Common absorbent has：Water, compound water solution, organic solvent etc..Absorbent must be able to and pollutant
Quickly chemical reaction occurs or pollutant can be promptly dissolved, and is convenient for analysis operation.Such as the fluorination in air
