Abstract There are many kinds of aerosol generation methods to make aerosol particles having wide dispersed sizes. Inkjet aerosol generators having an advantage in simple operation usually use to generate aerosol particles. In this presentation, we showed an inkjet aerosol generator for generation of bioaerosol particles with uniform size. Droplets generated from an inkjet nozzle, which contains PSL or Bacillus globigii spores, were continuously dried up passing in a drying module. Our inkjet aerosol generator can generate various sizes of uniform sized particle clusters. The clusters with the diameter of 2 to 8 um were successfully generated. Generated bioaerosols were shown to have a narrow particle size distribution. This system can be used in test and evlaluation of aerosol particle counters including bioaerosol detectors.
