Theoretical models describing the kinetic and evaporation as well as the electrical charge of droplets in a droplet chain generated by a vibrating orifice generator are presented. The models are verified by experimental results. Droplet charge and the electrical current transported by the droplet chain are correlated with the length of the liquid jet. Based on these results, an apparatus for generating neutral or predefined charged particles has been developed, whereby not only the average charge of the particle collective, but also the charge of individual droplets can be defined. The applicability in generating solid particle aerosols by jet dispersion of solutions are disclosed.
