Description
Technical field
The utility model relates to a kind of air organic contaminant sampling thief.
Background technology
Organic contaminant is meant the pollutant that the natural organic substance that exists with forms such as carbohydrates, protein, amino acid and fat and some other biodegradable artificial synthetic organic materials matter are composition.Organic contaminant is by medium circulation such as atmosphere, water and soil earth, and is human pathogenic by breathing, diet and contact organic contaminant.Existing air organic contaminant sampling thief must have aspiration pump, so inconvenient and can not use at areas without electricity.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of air organic contaminant sampling thief, and it is simple in structure, and is convenient and practical.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of air organic contaminant sampling thief, comprise the bowl-type sampling funnel on its top, the cylindrical shell of lower part and the joint flange that connects sampling funnel and cylindrical shell, joint flange comprises and sampling funnel upper flange that is connected and the lower flange that is connected with cylindrical shell, upper flange and lower flange faying face are provided with groove, be provided with the edge of admitting the disc filter membrane in the groove, upper flange and lower flange faying face also have gap, and the disc filter membrane is put into or taken out; Be provided with the solution absorbs thing in the cylindrical shell top, the lower end is provided with absorbent cotton.
Described disc filter membrane constitutes by gauze, quartz fibre filter membrane and wire netting are stacked in proper order from top to bottom.
Described cylindrical shell and solution absorbs thing faying face are provided with groove.
The utility model is inducted into disc membrane filtration mobile phone by bowl-type sampling funnel with air and does wet granulation, enters solution absorbs thing adsorbent solution phase organism then, obtains sampling, satisfies long-range conveying research of atmospheric pollution and testing goal.
