Master data.
Atmospheric sampling is the important step of atmosphere environment supervision, very big for the reliable sexual intercourse of Monitoring Data.Collection is big
The method of gas sample product, mainly there is two classes:The first kind is to make large quantity of air pass through liquid-absorbant or solid absorbent, absorbing or
Detention pollutant, get up the relatively low enriching pollutants of concentration in original air, such as degassing method, filter membrane method.Surveyed with this kind of method
The result for obtaining is the mean concentration of pollutant in air in the sampling time.Equations of The Second Kind is with container (vial, plastic bag, rubber
Bladders, syringe etc.) air of the collection containing pollutant.This kind of method is applied to following situations：The concentration of pollutant in air
It is higher；Or the sensitivity of assay method is higher；Be difficult by liquid-absorbant absorb or solid absorbent absorption dusty gass and
Steam.The result measured with this method is the instantaneous concentration of pollutant or the mean concentration in the short time in air.
With attention of the people to air pollution, the monitoring to air pollution becomes the topic of common people's care gradually, very
Many people want to oneself monitoring.Ordinary people realizes that a primary difficult problem for monitor air pollution is air sampling, and traditional is big
During gas sampling instrument collection air, the operation of many gas circuits connection is needed, usually allow the upper door operation of professional, and domestic consumer
Using it when sampling, it is easy to make a mistake.Such as absorption bottle is easy to reversed so that liquid flows backwards sebific duct and hangs liquid, causes follow-up
Sampling error；Every time one formaldehyde sample of sampling, needs 2 pipettings (to pour reagent into absorption bottle from package tube, gathered
From absorption bottle package tube is poured into into after again), it is easy to water clock, and residual of the liquid on tube wall is more during liquid relief, makes
Into sampling error.Additionally, when gathering pollutant using absorption tube, absorption tube is easy to reversed, causes sampling error.

This utility model is further improved, and the contact surface of the inwall of bottom bottle and the bottom of lid does frosting technology process, real
The sealing of existing contact site between lid and bottom bottle.
This utility model is further improved, and described absorption bottle also includes elastic seal ring, and elastic seal ring is fixed on lid
On body inverted round stage, the sealing of contact site between lid and bottom bottle is realized.
This utility model is further improved, and described instrument body is in integrally laterally disposed " H " shape, and left side is used to place inhales
Bottle is received, right side is used to place absorption tube；With solve the problems, such as existing sampling instrument need outside erection bracket, take up room.
It should be pointed out that the directivity word referred in this specification is explanation such as " left and right ", " left side ", " right side "
Direction in book accompanying drawing, just to convenient description, it cannot function as limiting foundation of the present utility model.
A kind of air sampling apparatus that this utility model is proposed, reduce gas circuit junction point, easy to operate, it is to avoid reversal connection；And
Without the need for liquid relief, it is to avoid water clock, residual is reduced.
