DEVICE FOR SAMPLING INDUSTRIAL EMISSIONS AND ATMOSPHERIC AIR Russian patent published in 2024 - IPC G01N1/22 

FIELD: measuring.

SUBSTANCE: invention relates to materials research. Disclosed is a device for sampling industrial emissions and/or atmospheric air, comprising interconnected by means of a detachable connection housing (3) and cover (2) with inlet (1), filter element (4) arranged on filter platform (6), wherein housing (3) comprises cutting edge (5), the inner diameter of which corresponds to the diameter of filter platform (6) located in the central part of housing (3), wherein device is equipped with punch (10) containing cutting edge (11) in its lower part and made with possibility of punching filtering element (4) with diameter equal to diameter of working surface of filtering element (4), and lower part of housing (3) is equipped with nozzle (7), inner diameter of which corresponds to diameter of working surface of filtering element (4), device is equipped with pusher (9) made with possibility of extraction of working surface of filtering element (4) from housing (3).

EFFECT: invention provides higher accuracy of quantitative determination of content of pollutants in industrial emissions and/or atmospheric air due to exclusion of stages of sample preparation from procedure of physical and chemical analysis, and also allows to use filtering element of small area.
