1. A nanoparticulate aerosol generator, comprising a compressed gas reservoir connected to a nanoparticulate material receptacle through a shut-off valve, wherein:
the nanoparticle material receptacle comprises an outlet hole for releasing nanoparticulate aerosol;
the generator further comprises a pressurized aerosol distribution chamber, in which the outlet hole of the nanoparticulate material receptacle is connected to or inserted into the pressurized aerosol distribution chamber;
the generator is configured such that by opening the shut-off valve, compressed air can instantaneously be released from the compressed gas reservoir to drive nanoparticulate material through the outlet hole into the pressurized aerosol distribution chamber;
the pressurized aerosol distribution chamber is adapted to maintain nanoparticulate aerosol at its interior within a controlled pressure, and the pressurized aerosol distribution chamber is equipped with an exit hole for the exit of the nanoparticulate aerosol out of the pressurized aerosol distribution chamber; and
ends of the pressurized aerosol distribution chamber consist of terminal closure sections, wherein the nanoparticulate material receptacle is inserted or connected through one of the terminal sections, and wherein a second source of gas flow at controlled pressure is connected through the other one of the terminal sections.
