Description
Technical field
The present invention relates to particle sampling technical field, more particularly to it is a kind of particulate matter on filter membrane can be carried out it is thorough
Cleaning, the particle analyte detection pre-processing device that simple in structure, the degree of automation is high.
Background technology
Atmospheric sampling is the process of pollutant sample or contaminated air sample in collection air.Spot sampling method has two
Class：One kind is large quantity of air is played the relatively low enriching pollutants of concentration in air by liquid-absorbant or solid absorbent
Come, such as degassing method, filter membrane method.Another kind of is with air of container (the vial, polybag etc.) collection containing pollutant.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 should be representative.Sampling efficiency is high,
Operation must be easy, and is convenient for subsequent analysis measure, to obtain the master data of reliable atmosphere pollution.Gather 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, and the reliable sexual intercourse for monitoring data is very big.Collection is big
The method of gas sample product, mainly there is two classes:One kind is to make large quantity of air by liquid-absorbant or solid absorbent, to absorb or hinder
Pollutant is stayed, the relatively low enriching pollutants of concentration in original air are got up, such as degassing method, filter membrane method.Measured with this kind of method
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 collection containing pollutant.This kind of method is 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, available for collection escaping gas and steam, such as alkyl lead.Liquid-absorbant in sampler is mainly used for absorbing gas
State and steam-like material.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
Hydrogen, hydrogen chloride are with water as absorbent；Sulfur dioxide can be used as absorbent by the use of tetrachloro mercury sodium；Thimet (3911), demeton
(1059) etc. organophosphorus pesticide can be used as absorbent etc. by the use of 5% methanol.Solid absorbent has granular adsorbent and threadiness to inhale
Attached dose two kinds.Common granular adsorbent has silica gel, unglazed pottery etc., the sampling for gaseous state, steam-like and particulate matter.Fiber
Shape adsorbent has filter paper, filter membrane, absorbent cotton, mineral wool etc., and suction-operated is mainly physical detention, for gathering particle
Thing.Sometimes adsorbent makes pollutant that chemical action occur with it and adsorbed first with certain chemical reagent impregnation, main to use
In collection gaseous state or steam-like pollutant.
Common outside atmosphere sample devices, it is small, easily carry, but the performance ratio of its detection is relatively limited, it is difficult to do
