Method and measuring device for the conduct and immediate evaluation of atmospheric pollutant analyses in situ

摘要

In order to allow a direct and accurate conduct and evaluation of atmospheric pollutant analyses in situ, a probe having an integrated detector and suction tube is introduced to the measuring location. The standard volume and the time for which the standard volume is pumped are communicated to a processor via a keyboard. Controlled by the processor and a mass flow meter, a vacuum pump sucks in the predetermined standard volume for the predetermined time. Depending on the type of detector, the quantity of the determined pollutant is communicated to the processor via an interface, the processor calculating the concentration of the pollutant in standard volume on the basis of the pumped standard volume and the quantity of pollutant, or a visual determination is carried out in the case of precalibrated adsorption materials.
