Abstract
The subject of the present invention is a method and a device for measuring the concentration of aerosols in a gas. The aerosol are dissolved in a solution liquid 16 contained in a leaktight enclosure 10. According to the invention, the aerosols arriving through a nozzle 32 impact, outside the liquid mass 16, on a continuous belt 20 which then conveys them into the liquid 16. Optionally, a brush roller 28 whose bristles are in contact with the continuous belt 20 allows the dissolving of the aerosols to be accelerated and the liquid to be homogenised. Application to the detection of beryllium and uranium in gases.
