For maintaining the inhalable pulverulent carrier substances and their properties when marker substances and/or active substances are applied, initially the substance to be applied is dissolved in a liquid, then the fluid is vaporized and finally the aerosol droplets are dried for forming aerosol particles whereupon the aerosol particles are whirled for being contacted with the pulverulent substance. The associated device comprises an aerosol generator 11 including on the nozzle-type, ultrasonic or other vaporizer for the substance to be applied, which is dissolved in a liquid, and a drying means for drying the aerosol particles so formed. Moreover, a mixing chamber 12 is provided for receiving pulverulent carrier substance and for establishing a whirling contact thereof with dry aerosol particles circulated and introduced therein.
