In a method for detecting and identifying bioaerosol particles in the air, the bioaerosol particles in a particle stream are selected in an ATOFMS (aerosol time-of-flight mass spectrometer) by means of fluorescence techniques, and only the selected bioaerosol particles are ionized, for instance on the basis of MALDI (matrix-assisted laser desorption/ionization), after which the resulting ions are detected and the bioaerosol particles are identified. The selection of bioaerosol particles takes place by means of laser radiation, generated by a first laser device, of a wavelength which in specific substances in bioaerosol particles effects a fluorescence, after which by means of a fluorescence detector the bioaerosol particles are selected and a second laser device is triggered to emit light of a wavelength which effects the ionization of the bioaerosol particles selected only by the fluorescence detector.

The invention is directed to a process and apparatus for preparing coated particles, in particular a process for preparing particles that are coated with small particles using electrospraying. The coated particles produced according to the present invention find use for instance as catalysts or as pharmaceuticals. According to the invention a host particle is contacted in a gas stream where it is allowed to contact with one or more moving tribocharging particles, thus providing a charged host particle, which is subsequently contacted with charged guest particles in an electrospraying step.

摘要:
A method, and an apparatus to reduce and remove liquid droplets in air, such as fog, mist, haze, spray or steam. The mist and/or air borne water or other liquid droplets catching and collection apparatus creates an “electric wind”, especially enforced by charged needle points or line arranged constructions and/or wires of the first electrode and an electric charging of mist and/or air borne water or other liquid droplets, which will be directed by the “electric wind” and the electric field between the electric source and the opposite grounded or opposite charged counter electrode (second electrode) of fine gauze or something comparable.
